Elephant

Preamp

Overdrive

Traynor TS50B preamp clone (Tronographic Rusty Box). Internal +/-15V charge pump, bypassable tone stack.

The Elephant replicates the preamp section of the Traynor TS50B bass amplifier, following the Tronographic Rusty Box schematic. Internally generates bipolar +/-15V from the 9V input via a charge pump.

Three-band EQ (Treble, Mid, Bass) can be fully bypassed via tonestack bypass switch. HI/LO input switch cuts gain and highs in Lo mode. Usable as a standalone preamp into a power amp or as a bass/guitar overdrive.

9V DC center-negative.
