Okay then folks. I had the amp apart at the weekend to track down a rattle (which I found!!) and didn't reconnect the reverb tank. I noticed it at band practice and reconnected it. Whilst I was there I spotted a jack socket right next to it, but no identifying marks as to what it was. I've had a look through the manual and can't find mention of it.
Anyone have any ideas what it's for?
Cheers!
