I have a TC Electronics RH750 which I've gigged with for around 8 years. It's a great amp. I never had a problem with the knobs but a couple of pre set buttons have cracked. I contacted them and they advised me to contact their UK distributor. I did this and paid and ordered three replacement buttons. This was over a year ago believe it or not. There have been many emails from me to Music Tribe and UK distributor but I still haven't received the buttons. Just wondered if anyone else have had a similar experience.
