JohnK Traynor TS50-B preamp pedal 2025 - Black/Silver (Rusty Box)

This is a Traynor TS50-B preamp in pedal form that I built sounds identical to my Tronographic Rusty Box (see last picture). The great thing about this pedal is that it uses a standard negative center 9 volt power supply. DO NOT USE A POWER SUPPLY HIGHER THAN ( VOLTS! It has an internal voltage converter that supplies the +15 and -15 volts required for the circuit. (the original Rusty box requires a 28-30 volt center positive supply). I used all high quality Wima capacitors and Lumberg jacks in this one.

it's comes in a 1590BBS which has the same dimensions as a standard 1590BB but is a bit deeper to allow all of the components to fit.
