Here's the next strike from BSM: a powerful preamp/booster! 40 years after the release of „Back in Black“ Bernd Meiser took the idea of Angus Y. playing not only live but also in the studio with his Schaffer Vega wireless device for extra gain, brillliance and compression. Bernd did not make a simple copy of the circuit but came along with his own ideas to realize the functions. It is designed to hit the high treble input of a British style amp with medium output pickups hard. What came out is a real monster, working from 9 to 18 volts.

The tube power amp simulator "Starbreaker" is based on the generation of an asymmetric "tanh(x)" as transfer function. It is - typical BSM - completely built with discrete silicon transistors and no OPs. By a mini-switch the overtone range can be manipulated in two ways. The unit works fine with all PU types but its design-center is a Strat with modern SC-PUs. The Saturation knob allows the adjustment of light crunch over fat sounds up to to hefty distortion. The Starbreaker works exclusively with +18V DC at 8mA current consumption.
