Many guitarists of the late 60s and early 70s knew how to get a rough earthy and unmistakable sound out of their humbucking pickups and tube amplifiers, which in retrospect has not been possible to recreate so far. BSM has dedicated so many booster pedals to this subject to receive these historical sounds with every tube amp, that offers a powerful clean or crunch character. But it ́s impossible to drive a treble booster pedal into saturation so the idea came up to develop a stand-alone version you can also use in front of a clean amp to get some crunch without the typical mid-honk sound and to replace the overdrive pedals on your pedalboard.

Heritage Crunch Booster

BSM decided to take the idea of this classic Rock sound and came up with a completely different solution to hit the target. Not interested in making a simple copy of the circuit but developing own ideas to realize the functions with silicon transistors. What you get now is a flexible high gain treblebooster/preamp combination optimized for medium humbucker pickups that works also very well with P90s and singlecoils. It is intended to hit the high treble input of a British Plexi-type amp (or other classic British oriented tube amps) hard. What came out is a real monster, working at 18 volts. But we have to admit that it still works very well with 9 volts, just a little less monstrous. It also comes with a status LED. The preamp stage is a mild treblebooster of low noise followed by a high gain silicon output stage that can easily be symmetrically driven into saturation.

Starbreaker Booster

The BSM J-Fuzz stompbox is a faithful recreation of the old original Jennings Fuzz from the late 60's. Tom Jennings was founder and master-mind of the VOX company in the late 50's, accompanied by his friend and technician Dick Denney, who engineered the famous VOX AC30 amp as well as the VOX Defiant transistor amp with a built-in fuzz circuit. Both amps became well-known and famous because of the Beatles, who used those amps.

The RPA Major is the answer to many customer calls, demanding the hard, agressive Ritchie Blackmore stage sound of the 70's, without the need to get their amp heavily modified. The RPA Major offers a lot more gain compared to the stock RPA model with tons of crunch and a higher level of agressivity ... something that fits the modern Metal scene as well. With the level control turned up to the max, the RPA Major delivers an output level of 8 volts (!!!), which can kill most modulation stompboxes with electronical CMOS switching like delay, chorus etc. that are connected after the RPA Major in the signal chain. So please only use the RPA Major with full level directly into your tube amp. If you want to connect some stompboxes after the RPA Major, reduce the level to 50% to be on the safe side.
