Title: VoxAC15CC1 tremolo
Post by: Latole on July 03, 2024, 06:50:19 am

Hi.

Does this Vox AC15CC1 require a foot switch to operate the tremolo?

I have this amp to repair.

1- poor reverb
2- tremolo doesn't work
3- change bright cap on volume

Thank you

Merlin you are right. no need pedal.

After disconnecting the pots main circuit from the main circuit to mod the volume treble cap and reconnected all plug in connectors, tremolo start working  .

 I believe that a slight oxidation of the contacts of these connectors could be the cause of the tremolo not working.  As a precaution, I sprayed some Deoxit on these contacts, sliding them several times to clean them well.

I pickup the pedal from my customer ; schematic is coming.
