This pedal is a combination Stratoblaster-Green Ringer-Orange Squeezer, wired together in that order. The Green Ringer section has a Tone switch – two different input caps that can be switched between for either a high freq or low freq (tone) effect. The Sting switch takes the Stratoblaster-Green Ringer out of the signal path, so the pedal can operate like it is just an Orange Squeezer.
This box has two boards inside. On one board, I combined the schematics for the Stratoblaster and Green Ringer that are posted at General Guitar Gadgets. I built the Orange Squeezer from the layout at Tonepad on the other board. After attaching all the necessary off-board wiring to both boards and wiring them together, I attached them to each other sandwich-like, with metal stand-offs.
