What our Customers Say
Matt Partner
I was recommend Sickamps by a friend who had used them to fix his amps and I have not been disappointed. Chris clearly knows his stuff and is very professional. He quickly diagnosed the issue with my Fender Blues Junior amp and also recommended updates to it that should reduce the likelihood of similar issues in future.
He turned the work around in just a few days which was a real bonus and more importantly, the amp now sounds great.
Thanks and I would highly recommend Sickamps. - 06/10/2025read moreread less×Matt Partner- 06/10/2025I was recommend Sickamps by a friend who had used them to fix his amps and I have not been disappointed.

SickAmps did a bang up job on my Meas Boogie Lonestar Special. I bought the amp five years ago, struggled for years replcing valves etc, getting the technicians in Denmark DStreet to help without success. Finally went to the place I should have gone in the first case and the amp is working like a gem. A number of issues identified and addressed very quickly all at a very reasonable price. One very happy customer. Thank you Sick Amps. Mike - 01/09/2025read moreread less×Mike Hickes- 01/09/2025SickAmps did a bang up job on my Meas Boogie Lonestar Special.
