History of the JAN97 Fryer treble boosters:
In January 1997 I made 2 treble boosters which were used in my Sydney workshop to help me ‘fine tune’ the sound of the handwound Burns Trisonic pickups that I developed for my 3 replica Red Special guitars ‘John’, ‘Paul’ and ‘George Burns’.
Hundreds of hours were spent making playing and assessing the sound of dozens of variations of my prototype Burns Trisonic pickups. To make my Red Special versions of the pickups I started by using Kent Armstrong’s 1990s re-issue Burns Trisonics, took them apart and made new bobbins which were wound with my preferred magnet wire and turns count (different for neck, middle and bridge pickups), used more authentic sounding isotropic ferrite magnets, and also experimented with various ways of damping down the microphonic feedback that the Burns Trisonic pickups have when they are used in BM treble booster mode at high Vox AC30 volume levels.
The pickup prototypes were loaded into my Guild Red Special guitar for assessment and played using a JAN97 treble booster through my Vox AC30 amplifier – at full volume to simulate how Brian May uses his AC30.
Countless dozens of variations of the pickup prototypes were developed in this way, all tuned by ear and LOTS of loud playing, with all variations of winding wire manufacturer, coil turns count, wire tension and winding pattern, magnet strength, damping rubber cushioning, wax and lacquer saturation methods, pickup heights etc recorded in my pickup book.
The goal was to get my versions of the Burns Trisonic pickups as close sounding as possible to the nuances of the utterly unique 1960s Burns Trisonic pickups of Brian’s famous Red Special guitar. The JAN97 boosters were an essential part of achieving that goal.
Later that year in November 1997 I took the boosters and my 3 handmade Red Special replica guitars to Brian’s Allerton Hill studio. Brian was so pleased with the 3 replica guitars and treble boosters that he asked me to stay in London and take apart and refurbish/repair his priceless original Red Special guitar, which was an extraordinary honour. Brian then used my replica Red Special guitars and treble boosters to complete the recording of his ‘Another World’ album which by November 1997 was around half complete. On the recordings Brian used all three of my Red Special guitars John, Paul and George Burns, and both treble boosters (which I now call type 1 and type 2).
On the JAN97 25th Anniversary re-issue treble boosters I am using the same vintage Dymo yellow embossing tape as on the originals, and the same 1997 batch ‘Fryer’ yellow logo waterslide decals that I used on the original JAN97 pedals and on the headstocks of my 3 Red Special replica guitars John, Paul and George Burns (pic below).

JAN97 Type 2 Treble Booster:
At Allerton Hill studio during February 1998 Brian May asked me if it was possible to reduce the top end hiss of the treble boosters. Top end hiss and noise is a common problem with this style of single transistor treble booster circuit.
I discussed the matter with my guitar electronics friend Colin Bloxsom who ran a guitar workshop in Sydney. Colin had been very helpful from the beginning of the Brian May project in 1996. One of the JAN97 treble boosters was then modified to have a 10K trimpot. This allowed us by using a small screwdriver to add some series resistance into the audio signal output of the BC182L transistor.
Brian and I then experimented as he played one of my Red Special guitars with the treble booster running through a Vox AC30 set at full volume. Brian played as I tweaked the treble booster’s trimpot back and forth from zero resistance to the full 10,000 ohms resistance.
From 0K resistance to around 5K the hiss began to be rolled off, and Brian thought that the point at which the series resistance began to effect the treble end of the audio signal was around 6000 ohms. This experiment guided the choice of using a 5K6 resistor at this point of the circuit in the 1999 ‘Brian May/Fryer Treble Booster’ pedal and in the early 2000s ‘Brian May/Fryer Treble Booster Touring’ pedal.

Diary and day book notes from Allerton Hill 1998 regarding the guitars, treble boosters and amps used by Brian May to record tracks on ‘Another World’ album:
From the time I arrived in England on 24th November 1997 until when I left to come home to Australia on 9th August 1998 I kept a diary and also made detailed records almost every day in my so-called ‘day books’ about the work that I was doing for Brian and everything associated with that work.
Often I made notes about which of my guitars Brian used to record with, and which treble boosters and amps were used for various tracks. Though often I was so busy with the Red Special repair work that I quickly took photos of whichever guitar was set up for recording in whatever rooms of Allerton Hill studio Brian chose to record on that day. (Usually Brian used the ‘guitar room’ but at times also set up in the large main room which has a very high ceiling – depending on the mic-ing and ‘room effect’ he desired).
Most of the information in my daybooks was concerning the work that I was doing for Brian in restoring/repairing/modifying his Red Special guitar, liasing with specialist people to assist with what I needed in my workshop for the Red Special guitar work and other BM projects; such as: paints (ie Richard Foxell and Martin James), specialist tools and workshop equipment, Vox AC30 servicing/mods (David Petersen), Deacy Amp replica project (again David Petersen), spray painting facility (Mark Reynolds from Leicester); and much more. Some of the information in these books are little gems which I haven’t read for nearly 24 years.
Much of the time during 1998 Brian was living at his Allerton Hill studio house (on the luxurious upper floors) which was situated around 45minutes south west of London. Because Brian was at the studio so often, this gave me the most extraordinary and wonderful situation of being able to speak with him on most days. I was also often fortunate to be invited to go out to dinner regularly with Brian and others, or to go swimming on weekends when time was available. This allowed me to not only get to know Brian very well, but to also have the opportunity of discussing with Brian at length such issues as his guitars treble boosters amps, making his Red Special with his dad Harold, his growing up at Feltham with his Mum and Dad, the legendary Deacy Amp, and about Brian’s fantastic musical life with Queen over the years and the characters they encountered.
Looking back now from this time in 2022, it was truly a most extraordinary period of time for me, and indeed a great honour and a privilege to be trusted by Brian May to look after his Red Special guitar and his other equipment.
Some entries in my diary and daybooks list which guitars treble boosters and amps Brian used to record various tracks. Sometimes when I arrived at work in the morning at Allerton Hill studio I took photos of guitars still set up and plugged in from Brian using them to record tracks the night before. I have hundreds of photos which I will hopefully will get time to sort through soon, and may hopefully have some of interest to post up.

January 1998: Fryer Red Special ‘Paul’ still on the stand and lead plugged in having been used by Brian May to record with the previous night. Guitar is in main large room and in front of mahogany Rose-Morris AC30 circa 1990 only there for its decorative function and not used for recording.
