I've lived in Manchester for a couple years now but wasn't aware of any shows...but I'll admit I'm not really 'in the loop' about such things. I'll have to look into it!
I did have a few Zed amps...I got rid of them in pretty short order though. They were first generation and I knew that they could have issues so I tried contacting Zed to get all the upgrades done...however 3 emails, a voicemail, and not a single response later I decided they weren't a product I wanted to have, nor was Zed a company I wanted to get 'service' from...so I found them new homes.
