The amp is great for acoustic guitar, I found that I needed to turn the trebles down quite a bit though as the piezo tweeter can give it a bit of a thin squeakiness. But after a bit of tweaking it sounds great and it's got a pickup and mic input - so I could technically plug my guitar in
and mic it up, and have a balance between both inputs. Although I don't have a dynamic microphone so I've just been practising with the pickup for now.
Please keep me in the loop about your open mic in Exeter, I'll come along and play!
And let me know if you have any gigs!
