Yeah my Fender champ 100 amp acting fuuny. The TAP button on the #2 chan side comes on when i don't want it to! It came on at rehersal the other night,and i got a little peed & I pounded it 1/2 hearted above the Tap button on top of the amp it self and it went off! This is on the FX select # 2 chan side @ reverb pos, i dont want it ON ! or Tapping!!!! How can i make it quit? I know this it probably operator head space on my part. HELP! Its only 18 months old just hope i dont have to have it put in the shop. How do you cut the TAP off!!!! I know hitting it on the top of amp is not right! but it made it stop! & got the sound back that i wanted! Whats happening here somebody?

Is that feature also controlled by an optional footswitch? If so, plug in the footswitch and see if you can control it that way.

I mention this because many amps that have optional footswitches use a switching jack that re-routs the control signal from the front panel to the footswitch. These switching jacks have very small contacts that easily become fouled by dirt, dust, or bellybutton lint.

Plugging in and unplugging the footswitch several times often clears up the poor contact in the switching jack and makes these sorts of ghost-in-the-machine occurrences disappear.
