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.
