Our new British Boost is based on famous Brian May Booster from the 1970’s. A diagram of this booster was given out by DiMarzio and Guild in the early eighties when the first Brian May guitars came out. Guild later offered a booster for the first BM guitars but it was quite different than this circuit. Our offering is taken from the hand drawn schematic that Guild traced from Brian’s personal treble booster. Guild and DiMarzio both stressed that in order to get The BM sound a booster was a key ingredient. If you want to heat up your amp with a cranked AC30 type of tone, try the British Boost.
