It is a modified guitar effect SansAMP GT2 with mids control, emiter follower at the output and with input modification – giving the signal from the first follower to the „distortion” system. There is also an additional effect setting (with 4-position switch).
Housing was made of cable conduit – it was cut, bent and soldered. Panel was designed in FrontDesigner. Slide potentiometers are not typical for a distortion.
Chips:
TL082CP at the input x1
TLC272CP for the distortion x2
uPC1458C for the equalizer x2
The PCB was made in „almost thermal transfer method”. Top and bottom of the PCB was printed, then glued on a cardboard, holes were made using a needle. Then the components were placed on the PCB and linked together with protruding wires.
