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. 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 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, and has the same perimeter as a Rusty Box, but is vertical instead of horizontal
