Thank you for your advice. Unfortunately, it still doesn’t work. Having no experience of electronics i’d rather not go fiddling around inside with loose wires.
I’m sending it back and buying a brand new one next week.
The guy who I bought it off is going to get it repaired for me. If it can’t be fixed he is giving me a refund. Shame, I have wanted to get my hands on this for ages. It’s a great pedal.
