My Marshall AVT 50X combo amp.

It has a noisy volume knob on the clean channel. Didn't respond to a clean with contact cleaner so may need replacing by a qualified engineer.

I've attached some good quality castors to the base. I appreciate this may put a few people off so it's reflected - along with the faulty knob - in the price.

Going on ebay tomorrow for £50 to start but if you want a decent amp, perhaps for home use of a backup and don't mind picking up in the Warrington area then make me a sensible offer and i'll pull it from sale or alternatively make a bid on ebay.
