Ibanez Phase Tone

[tman]

Hello

I was just given a Ibanez Phase Tone script pedal I have taken photos of it however I can email them if someone can post them. Is there a schematic for these as it is cosmetically fine however the effect doesn't kick in are these worth anything ?

I'm sure there is a ckt for this on-line.

This one was very similar,

I'd check
- the switch
- the electrolytic cap between the JFETs and the VCO
- perhaps try to adjust the bias trim pot (this requires very fine adjustment)

There's a few version of the Phase Tone as well-IIRC quite different from each other.
