Oliver Leiber from Ollywood Studios USA testimonial

•August 27, 2009 • Leave a Comment

Well known Hollywood Hills record producer Oliver Leiber has been using several of Greg Fryer’s handmade Brian May effect pedals as well as a custom Greg Fryer handmade AC30 amplifier for several years now and has updated us about his equipment and also about what Red Special guitars Oliver has been using for his recording work.

” Hey Greg, I’ve been enjoying recording with your amp and pedals for years now! I can’t tell you how much great use I get from them!!! I’d like to buy a Deacy Amp soon so please let me know when they’re out.

OK the gear that I use: in the studio my “go to” treble booster is my early issue maroon BM treble booster that you handmade for me in 2001. Its not the Plus Deluxe or Touring which I also use but your original handmade one. If I am looking for a “bit more” for a specific kind of lead tone, I will switch out to the Treble Booster Plus sometimes which definitely pushes the amp more and makes the sound more saturated which works nicely for single line stuff….

I have the Touring booster on one of my pedal boards which I bring in and out using a loop switcher….its also a great sounding pedal!

If I find myself in a recording situation where I don’t have a great AC30 handy and I’m staring at a Fender Twin or something super clean sounding with nothing but clean headroom, I’ll bust out the Fryer Mayhem pedal which gets me pretty close to where I like to be in that world!

As for the Fryer AC30 that you built for me, I really love both channels!! When I’m going for the Brian May thing its all about your Normal channel throttled with the treble booster in front….stick a Shure 57 and a Beyerdynamic M160 on one speaker and I’m off!!!

As far as BM guitars, well I am using BOTH a Guyton and a Kz Pro Red Special. They are both excellent guitars with incredible attention to detail and finish. At that level of quality building I would say it comes down to “different” rather than “better” in comparing the two. By virtue of the fact that they are different pieces of wood with different pickups, each has a setting or two where it seems to really shine and “speak” the best. Admittedly it is a great luxury to have both to choose from at any given time, and I would be truly happy just owning either one! Nuf said about the guitars….

Cheers,

Oliver”

Experimenter’s DIY Treble Booster schematic

•August 26, 2009 • Leave a Comment

Suggested range of values for the experimenter’s DIY Treble Booster schematic: alter component values and transistor types to suit your musical tastes and amplifier requirements.

Capacitors: C1:1nf to 22nf, C2: 10nf to 100nf, C3: 10uf to 470uf electrolytic, C4: 10uf to 220uf electrolytic

Resistors: R1:100K to 1M, R2:100K to 470K, R3:22K to 68K, R4:4K7 to 10K, R5:1K to 3K9, R6:22K to 1M, R7:0 ohms to 1K.

Other things to try: resistor R”X”: 0 ohms to 2K2 this will tend to change the upper mid “focus” of the booster sound with values closer to 2K2 smoothing out this mid focus and lower values (esp 0 ohms) giving a harder more direct rangemaster type focus. Like all things, alter to suit your taste. Capacitor between transistor base and emitter 100pf to 2n2, series resistance between C2 and R6, capacitor between output and ground, R6 resistor as a output level pot, R1 as an input level pot, series resistance up to 1K at input C1 to assist with RF rejection, R4 collector resistor configured as 10K level pot as per original 1960s rangemaster booster circuit.

Transistor Q1: 2N3904, 2N5088, 2N5089, 2SC1815, 2SC732, BC107, BC108, BC109, BC182, BC183, BC184, BC149, BC173, BC546, BC547, BC548, BC549, MPS8098, MPSA05, MPSA06, MPSA18, MPSA20 as well as other suitable NPN transistors

Without prejudice.

Fryer Sound Ltd would like to state that recently Mr Covington from the USA attempted to purchase one of our Brian May treble booster pedals from our USA dealer Sphere Sound and then cancelled the order a few days later. Unfortunately the intending purchaser’s name was leaked from within Fryer Sound, something which we have since apologised to Mr Covington for. For the avoidance of doubt, we would like to make it clear that our dealer in the USA Mr Scott Van Dusen, his company Sphere Sound and its employees had nothing whatsoever to do with the leaking of this information.

Yours sincerely,

Greg Fryer and Nigel Knight

Fryer Sound Amp Protector

•August 4, 2009 • Leave a Comment

DON’T FRY YOUR AMP!

The Fryer Amp Protector has been developed due to a request from a client of ours who struck trouble recently when his band played at a local hall in the UK. The mains power supply should have been close to 240V AC, but due to an electrical wiring mistake was substantially higher. What resulted unfortunately was damage to the band’s expensive vintage and boutique amplifiers.

The Amp Protector protects your amplifier from the damage that can happen to transformers, valves and circuitry from higher than normal voltage in the mains supply.

This can occur when playing in situations like village halls, outdoor or mobile locations, cruise ships etc or any time your amp is likely to encounter a fluctuating mains voltage, badly wired up mains supplies or fluctuating supplies from generators.

The Amp Protector is put in the mains line before the amp. If the mains voltage goes too high or too low, the unit cuts the supply to the amp before any damage can be done.

On the front panel there is a digital readout which shows the incoming voltage, and below that is a bar of LEDs that shows you clearly from a distance that all is well (or not well as the case may be).

The Fryer Amp Protector is cheap effective insurance for your amplifier regardless of whether you play a vintage/boutique amp or not because of the cost and inconvenience of expensive amp repairs. With valuable vintage amps, sometimes damage to transformers and vital components will change the sound of your amp forever even when these components are replaced with modern equivalents.

For Brian May fans, one of these units will happily protect all three Vox AC30s. Amps would have to be switched on one after the other, and not all at once because of the inrush/current draw from each amp’s mains transformer as the amp gets turned on. In this situation simply wait a few seconds before switching on the next amp.

Amp Protector for USA/Canada/Japan mains power 100V-120V AC will be available in the near future. Please watch our website for updates.

Frank Rohles’ CD “Time”

•July 27, 2009 • Leave a Comment

We are pleased to have Frank Rohles’ new CD “Time” available on our webshop. In 2004 Frank Rohles was chosen by Brian May to be guitarist in the We Will Rock You theatrical production in Cologne, Germany. The Cologne production was extremely successful and played thousands of shows running from 2004 until 2008. Brian also asked Frank to be guitar supervisor for the Zurich and Toronto WWRY productions when those shows were being set up.

Please click here for Frank Rohles’ website and more info about his guitars, equipment, WWRY, recordings and musical projects etc

Frank has used the Brian May Fryer Treble Boosters and the Fryer 1 Watt Amp extensively throughout the recording of “Time”, and has also used the new prototype Treble Booster Special and Vari-Booster pedals.

Frank has sent a list of the gear he has used:

“On this record only one thing stayed constant: every electric guitar track was played with my guitar Pearly.
Through the recording I’ve been mixing lots of different sounds and amps, guitar settings, picks (have used simply everything), to get the different textures on the songs. To get the ‘wall of guitars’ rich and fat rhythm sounds on these songs I have used my Vox AC30 TBX amp being driven by the Fryer Treble Booster 2002 going into a Damage Control ‘Liquid Blues’ overdrive pedal.
(** See below for 2002 Treble Booster and Damage Control ‘Liquid Blues’ info).

The Normal Channel of the AC30 is used with its volume level set around 1/3 level.

You can hear that on songs like ‘Time’ (track 04) on the last choruses, when everybody thinks this is it, it can’t get any fatter….sure it can and it does! This combination of equipment allows you to still get even more fatness but to keep the detail of everything and get it sitting properly in the mix which sometimes is hard to do with fat layered guitar sounds. Listen to the additional rhythm guitars coming in at 03:42 on this track ‘Time’. To me it blows everything away!
You can find similar rhythmical fatness on tracks like ‘Best of men’ (track 08) and in the choruses of ‘High and Low’ (track 9) plus other examples on the record.

There are many sonic examples that I can mention for lead guitar: a nice rich solo humbucking sounds on ‘Best of Men’ (track 8), ‘Go Your Own Way’ (track 01), ‘She is my Life” (track 05). Also great singing neck single coil sounds on ‘Now That We’ve Made It’ (track 03), ‘Here’ (track 07) and ‘Too Late This Time’ (track 10).
And nice crisp crunch/nearly clean (but with good headroom) rhythm sounds on ‘Too Late This Time’ (track 10).

Examples of playing with a titanium pick (sounds metallic like Brian May’s sixpence) and some May-ish rhythm sounds for ‘The Centre Of My Life’ (track 11) and ‘Desert Of Love’ (track 12).

I’ve also been using the Fryer 2002 Booster in combination with some other preamps like the Hughes and Kettner Attax or Tubeman. With this combination I’m able to get more American sounds without losing the richness or dynamics of the booster. I love these kind of sounds on songs like ‘Honesty’ (track 02 Choruses) where you can hear it as a complement to the ‘Rectifier’ type sounds. It pops up nice mids in an otherwise hard tight sounding mix…also the solo of this same song using a wah pedal with the 2002 booster.

Other songs that show the versatility of using this treble booster in combination with different amps are the rhythm guitars for ‘Pressure’ (track 06), same sound is used for rhythm guitars on the funky sounding ‘High and Low’ (track 09) verses. This uses Bridge & Middle Single Coil > Fryer Booster > Univibe > Attax Preamp > AC30. ‘High and Low’ choruses use Bridge and Middle humbucking > Fryer Booster > Attax preamp > AC30.

Last but not least are the 2 ’secret weapons’ which have helped me create some unique sounds here:
* The Fryer 1 Watt Amp is used for solo sounds on ‘Pressure’ (track 06), Guitar Orchestra sounds on ‘High and Low’ (track 09) and again on ‘Pressure’. Spanish trumpet ‘Deacy-like’ sounds use the 1 Watt Amp on ‘Desert of Love’ (track 12).
* The Vari-Booster prototype pedal is used on solos for ‘Centre of My Life’ (track 11) and ‘Desert of Love’.

Acoustic guitars used are: Takamine 6 string western EN-10C, an Ovation 12 string western, a Takamine Spanish guitar, and a Bruko Ukelele. A Sandberg 5 string bass played through an Axe FX Ultra. The Axe FX Ultra has also been used a lot on the whole production.

Most used electric guitar sounds from my homemade ‘Pearly’:
Rhythm guitars use mainly either bridge humbucker or bridge & middle humbuckers together.
For soloing: bridge & middle humbucking together, neck as single coil and as humbucker, neck & middle out of phase, neck & bridge out of phase, and for some ad libs: bridge pickup as single coil and bridge & middle out of phase.

I love experimenting by using a lot of little effects on each song for some surprises over short moments. For this I’ve been using (among others) effects like Univibe, Chorus, Delay, Tremolo, some Wah pedals, Leslie and a lot of incredible pitch and space sounds.

Thanks and I hope you enjoy listening to my new recording!

Cheers,
Frank Rohles July 2009 “

*Footnote: Frank’s 2002 Treble Booster is a standard light blue colour Brian May Fryer treble booster featuring a level control. In 2008 Greg re-created this particular booster for Frank featuring the same components that he was using at the time in 2002 but instead housed it in a bare aluminium enclosure featuring a battery box on the side and no level control. This booster is very similar in its circuit and components to the Fryer Treble Booster Touring pedal.

Please see Frank’s Vari-Booster pics below to view the 2002 version booster which is on top of the Vox AC30 at the right hand side of pic.

Mp3 music tracks from Frank Rohles on the webshop:
1. “Appetizer” is a medley of several tracks from “Time”.
2. “Desert Of Love” is a new instrumental version of his album track which Frank has kindly done for our website.
Frank tells us that he has used the following guitars and pedals for this instrumental:
“The additional guitar is again Pearly played through the “Treble Booster Special” prototype with the Vari-Booster pedal kicked in at times. I have also brought up the volume of the 1 Watt Amp’s “spanish trumpets” so that now without the vocals of the album track they are much more prominent. I hope you like this version. Cheers, Frank”

Vari-Booster pedal

•March 11, 2009 • Leave a Comment

The Vari-Booster is a new product coming soon.

Our prototype has been used recently by Frank Rohles on tracks for his soon to be released CD “Time”.

At this point we are not sure what the retail price of the UK made Vari-Booster will be, but we expect it should come in between 185-210 GB Pounds. Further info will be posted soon when available.

Frank’s comments about the Vari-Booster and his soundfile samples taken from the CD:

Greg, here are a few snippets of songs from my CD in a kind of medley where the 1 watt Amp and the Vari-Booster have been used.

I have used the 1 Watt Amp in some parts to make “Brian May-ish” sounding orchestrations, but a little different maybe to what Brian would have done….

The first part is one of them over the riff, then the bridge with some left/right harmonies, and then the end part with the ad libs and the ending harmonies.

The second song includes a solo using the Fryer 2002 booster (a recreation of a particular Fryer standard Treble Booster with level knob made for Frank in 2002), and the Vari-Booster being driven by the 2002 booster.

The third song includes again some harmonies over the riff – this is only a short part.

The last song has some “Spanish trumpets” using the 1 Watt Amp, and the last solo is played with the Fryer 2002 treble booster and the vari-booster.

Greg, I’ve been fooling around with the pedal on this recording and I really like it!! In my opinion it does a very good job to get more distortion and lifting tones after a treble booster – for soloing or shredding :-)

The vari-booster can give very recognisable sounds for soloing (think of Carlos Santana), or can be used as a “magic weapon” set up in ways for individual soloing. I’ve been recording my new CD and its been great to use the prototype vari-booster and the 1 Watt Amp on a few songs.

Wide/narrow positions: I like the wide position best because it keeps more harmonics on the sound. The narrow position can be very extreme and focussed, but the taste of every player is different so it is a cool thing to have these choices. This pedal’s sound can really burn if you want it to, but also is capable to give a sweet singing tone. I’ve also done some long standing feedbacks with it, and its sound reminds me of when I have used a wah in a set position, but this pedal sounds better and different than the wah.

Cheers,

Frank

Brian May AC30 modifications: Peter Michalowski version

•March 5, 2009 • Leave a Comment

Over the past year Greg has worked with both Mike Ryde and Peter Michalowski on modifications to their Vox AC30 Brian May amps. Both Mike and Peter are very experienced with the Brian May guitars pedals and amplifiers, and feel that their AC30 BM amps have been much improved soundwise by these mods.

Please click here for Mike Ryde’s website where you can download a pdf file about modification of the AC30 BM to the Dave Petersen BM spec. Mike’s site is extremely informative about his experience with the Brian May equipment in general.

In late 2008 Peter Michalowski from Sweden had his amp tech Ola Lehnert do the mods that Greg Fryer suggested, and together through 3 versions of the mod they experimented to tweak the amp to what Peter thought sounded best.

Ola Lehnert is a well respected amp builder and repairer in Sweden.

For Ola’s website see www.lehnert-amps.com

Click here to read Peter Michalowski’s comments about the BM AC30 mod and to hear his soundclips of the Greg Fryer and Dave Petersen modified BM AC30s.

Below are Greg Fryer’s schematics of the Peter Michalowski version of the AC30 BM amp mod.

Warning: please bear in mind that this sort of modification voids the warranty of your Vox AC30 BM amp, and that amplifier repairs and modifications should only be carried out by experienced qualified technicians.

Double warning: guitar amp modding can be a fun home hobby if you become experienced in valve electronics, take it VERY seriously and read up bigtime about it, but because of the high voltages involved it can also kill or seriously injure you and its not much fun playing your super hot amp with your super hot guitar when you’re dead! So if you’re interested please ask your amp tech to do this work for you.

More details soon for the BM AC30 regarding which component numbers and turret post numbers etc are involved. Mike Ryde’s website pdf document gives a very clear view of all this too.

Coming soon: improved Vox AC30 standby switch system for both GZ34 and silicone diode rectifier amps.

But for a GZ34 rectifier AC30 you really don’t need a standby switch at all. Just leave your standby switch in the ON position permanently, and turn the amp off and on by using the Mains On/Off switch. Your GZ34 will last a LOT longer this way.

Click here to read Lyle Caldwell’s excellent in-depth article about why you don’t need a standby switch on a GZ34 rectifier AC30 at www.vintageamps.com/plexiboard/

AC30 suggestion: if you need to mute the AC30 for guitar or pedal changes or whatever, simply pull the guitar lead halfway up out of the black plastic input socket. This will earth the signal going into the first valve thereby muting the amp. And you don’t have to scramble around looking for that guitar lead on a dark stage…

More soon.

Custom transformers from Greg Fryer’s handmade Brian May and WWRY AC30s

•March 4, 2009 • Leave a Comment

The high quality handmade transformers developed for Greg Fryer’s custom amps made for Brian May and the WWRY productions are now available. (** Please see note below 9th November 2009)

These replacement transformers are suitable for fitting to the UK made 1994-2004 TB/TBX series Vox AC30 as well as the Chinese made AC30 BM and the AC30 CC amps.

Background info about the WWRY AC30s: the London WWRY production has been successfully using Dave Petersen’s custom made amps since 2002, whilst the productions in Australia, Japan, Sth Africa, Sth East Asia, Canada, USA, Germany, Zurich and Austria have used Greg Fryer’s handmade amps.

The Petersen and Fryer amps share several similarities but also have other differences in concept and circuit, and have been developed independently of one another. Both amps use Dave Petersen’s idea (borrowed from the early AC15) of having the whole HT B+ supply filtered by the choke, although Greg and Dave have pursued different ways of approaching the running of the EL84 power valves and are using different voicings and drive levels for their preamps. Both amps also use different methods of safety cutout for when the EL84s become overstressed.

Greg felt it important when he was developing his amps in 2003-4 to also develop high quality handmade mains, choke and output transformers for the WWRY and Brian May AC30s. This was because of the reliability and quality problems that had been experienced with the mass produced UK Drake and Dagnall transformers from the 1994-2004 Vox AC30 TBX series.

After many thousands of hours being played loud in the WWRY productions around the world and with Brian May on stage during the Queen + Paul Rodgers 2008 World Tour, these special handmade transformers have proved to be very reliable and also very good sounding. The transformers have been developed in Australia with the valuable assistance of several experienced amplifier and transformer specialists from Sydney and Melbourne, and are made in similar ways to the great old Vox transformers of the 1960s and 70s.

Particular attention was devoted to the development of the output transformer so that it produces the right tonal and distortion characteristics, with several variations being trialled and assessed by Greg Fryer during 2003-04.

(9th November 2009: please note that our custom transformers are no longer available for sale. We recommend that you consult your amp tech about suitable replacements if needed or contact Mercury Magnetics in USA, Heyboer dealers in USA, or Dave Petersen/Shere Sound in UK)

Please also see the vintage amps forum at http://vintageamps.com/plexiboard/ for an excellent source of Vox and other amp info.

1 Watt Amp Kit drawings and schematics

•February 25, 2009 • Leave a Comment

Speaker cabinet drawings and schematics from our build-it-yourself 1 Watt Amp Kit.

As many people might know, the 1 watt amp kit is based on the old Mullard 1 watt amp design with a few custom changes and new transformers that we have developed through our Brian May Deacy Amp research. More background info about the differences between the 1 watt amp kit and Brian May’s original Deacy Amp soon.

The 1 watt amp is powered by the large 9 Volt PP9 battery and can also run from the smaller 9 Volt PP3 battery, although the sound will be different when using a PP3 (which is the battery most commonly found in guitar effect pedals). We are planning to soon have available a 9 Volt AC adaptor suited to the 1 watt amp kit.

More 1 watt Amp Kit soundfiles from Frank Rohles soon featuring the 1 watt amp recorded using a new prototype pedal which produces some very exciting new sounds.
