Back in the day when I owned one of these, they sent me out some bits so I could replace them myself. Great service.
Just a note re: sending it back to them - if you need to be careful you don't get stung by the Inland Revenue when it comes back.
Oh God... the one that got away!
I always wondered where it ended up.... gah!
Here it is in action. I'm off to smash open my piggy bank and see how much is in there.
IME the bigger the venue, the less relevant the backline (IME).
It's the clubs and bars where this is especially important to me. I want that tactile feedback.
