Colorsound Supa Tonebender service

A Supa Tonebender in near mint condition, giving a very weak output signal.

Guts reveals what appears as all original.

Signal generator and a scopemeter isolated the problem to the bypass switch.

Not the typicall bypass switch construction. Note the date stamp 10 MAY 1976.

However a construction that is easy to service.

After a cleanupof the switch and the Radiohm potentiometers, the pedal is back in working condition.

The depth pot made no change and you could rotate it with no stops. A view of the pot dismantled.

Broken Boss CE-2 depth potentiometer

As the pot was beyond salvation, the pedal got a new one installed.

A customer asked for a mod of the bypass switch for the wah circuit, omitting the volume function when the wah is set to bypass, and service in general.

Cleaning the wah pot, recapping the circuit board and rewiring the wah/volume switch and the pedal is as new again.

Vintage Vox Wah-Wah

Saving a vintage wah pedal.

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.

Vintage Vox Wah

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.

Vintage Vox Wah

Rewired with a new battery clip installed.

Also replaced the old 4,7uF capacitor, for some reason it had a non polarized version.

An old Sovtek/Electro-Harmonics Small Stone in need of some service.

This old pedal was plagued with a ticking noise from the LFO. After some tendering it’s once again usable.
