It has been something i have experience for a long time. A lot of the amp builders didnt care about it, so they never did anything about it. But they werent playing fast enough i guess to fight for clarity with unnecessary microphonic static.I'm delighted for you. Then you have made a good choice.
But unfortunately it is actually the case that there are a lot of more or less useless amps on the market.
I already had well-known amps on my bench and was about to start troubleshooting until the owner told me that all of these types had so much background noise. I don't want to mention names.
