Schaller - Wau-Wau bow-wow + Joi-Joi
“... 1966 First Generation ... the 9V battery connector may have been replaced, and there is a small cut in the insulation of the output cord, as it was stored in the box with the cord wrapped fairly snugly around the pedal and there was no strain relief installed. ...
The "Bow-wow" selection sounds like a traditional wah, with good and ample linear sweep, while the "Yoy-Yoy" selection sounds like some sort of controllable flange effect. With a good amount of reverb, you can get some pretty ridiculous sounds from this thing. As far as functionality goes, the forward input sounds excellent with a guitar and traditional tube amp, while the rear input appears to serve as a mic or other instrument input (the manual mentions a trumpet, for example), and sounds a bit weaker. The manual states different resistances for each circuit. The manual also depicts an XLR-type microphone jack for the rear input, but I believe this pedal was made with two 1/4" input jacks from the factory, as there are no extra or larger holes surrounding the rear jack where the larger XLR jack and plate would have been installed. “
