Alembic Stratoblaster

The Stratoblaster was originally built as an onboard preamp that could be mounted on a Strat in place of the normal output jack canoe. The gain was adjusted by a trim pot (so no external knob), but the circuit provided 3-14 dB of clean boost. It's a great simple circuit and can fit in a 1590a or you could build it into a guitar (for all you Grateful Dead fans out there).

    1. Those are the potentiometer lugs. If you're building it into a pedal, see the General build notes for how to wire it with a footswitch. If you're building it into a guitar the concept is similar to what's described there too. And Google is always helpful.
