I'm selling a Marshall JVM2 50 Watt Head for £500 ono (Perfect condition, including a programmable footswitch). I don't need it anymore as I'm buying an ENGL. It's around 5/6 months old and has recently had a change of tubes, the amp in controls and features is very similar to an ENGL Powerball with a bit less gain. People will probably argue with that, but meh.

If you want any more details about the amp:
I'll update this sometime when I can be bothered.
