Mokl Posted July 31, 2022 Share Posted July 31, 2022 My go-to guy has retired, and I find myself needing a repair to my Thunderfunk 550 head. It works fine, but intermittently and without warning, puts out a horrendous screeching through the speakers Anybody able to recommend a good amp tech? Ideally in the Herefordshire area, but I'm willing to post if further afield. Love this amp, and they're supposed to have been designed with repairability in mind... Thanks in advance!

scalpy Posted August 1, 2022 Share Posted August 1, 2022 I’d also be interested, my long serving Markbass is not in the rudest of health as well. Quote Link to comment Share on other sites More sharing options...
