From the post
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).
