A vintage Vox wah pedal giving no effect. The pedal had the jacks, bypass switch and the potentiometer changed before it was sent to Zeta Sound.
Has the number 250.049 at the bottom lid as the only identification about what model it might be.
The bypass switch was replaced with a new DTDP switch, although wired wrong. Got it rewired correctly, but the pedal did not give any effect. The problem was the new potentiometer, too much heat when soldered had caused the wiper soldering lug to lose its contact. By taking the pot apart and reattach the rivet it could be saved.
Rewired with a new battery clip installed.
Also replaced the old 4,7uF capacitor, for some reason it had a non polarized version.
