View Full Version : Can't Turn Off Verb/Trem (Vox AC30CC)

I've done searches and I'm either using the wrong search criteria or this isn't a common issue.
I can use the footswitch to turn on/off the verb and trem on my AC30CC, but if I completely unplug the footswitch they both turn back on again. To combat this when I use the amp without the footswitch I've just been turning the controls on both to zero, but I'd rather that they were both completely off.
Is there something wrong with my amp, or is this normal behavior?

Mines the same (AC30C2), and my vibro champ and Princeton reverb are as well. Pretty sure you need the footswitch in order to turn them off. Otherwise, you may not be able to turn them 'on' if you didn't have the footswitch.

Balls!

I have the footswitch I just never use it. I've been leaving it connected and in the back of the amp, but it rattles.
Yep, you need the foot switch to turn them off. Kind of annoying. Even with the controls turned all the way down the trem and verb introduce noise.

I owned one for a short time, and I never noticed any noise with the knobs dialed back to zero.
Did you try plugging in/unplugging the foot switch? There's more hiss with it unplugged. Could just be my particular amp, but I doubt it.

More noise and I can hear a tonal difference between having the Trem on @ 0 and having it off. Slight, but it is there.

For what it's worth, I can hear no difference between all knobs at zero and "off" with my cc either in terms of hiss or tonally.

You can take a voltmeter, unplug the foot switch. Test the plug from the footswitch that goes into the amp. If it has dual functions, it's probably a stereo 1/4" plug.
Before you unplug the footswitch cable, however, put the switches in position to turn off reverb and tremolo.
With the voltmeter, test continuity between all three points on the plug.
Map it out on paper.
Purchase a 1/4" right angle or straight plug at an electronics store or on-line.
Wire the plug up with little jumpers so that it mirrors the conditions you mapped on the footswitch plug.
Then you can just put your wired up plug in the hole, and leave the footswitch in your bag or at home.
