I purchased S1 pro about 1.5 years ago and while playing the concert recently , 5th string started to buzz through S1 pro, even when barely touching it, the buzz spread to B note on second fret. No buzzing on the guitar itself, only when amplified. Any advice? Thanks!
Are you using your ToneMatch mixer (mentioned in your other post How to connect S1 Pro to ToneMatch to Bose T4S Mixer)?
Have you been able to replicate the problem in a different physical setting?
Yes, it happens in any situation ; with or without T4S mixer
Have tried a different guitar connected directly to the S1 Pro?
