Since this pedal requires two 9V batteries I had it modified with a charge pump allowing it to take a normal 9VDC adapter or one single battery. In the now empty battery compartment I added a pot for the output volume.
Installed a threewayswitch wich in left pos lets the circuit clip over red leds, centerpos no diodes and right pos silicone diodes. Replaced the Boost switch with a stompswitch and a indicating led in its original position.
Added some images from a rehousing project of a Danelectro Transparent Overdrive.
The classic Boss CE-2 chorus moded with chorus/vibrato switch and a speed range selector switch.
