1 Zigracer 2 years ago Last night had a weird problem with my Victoria (Gretsch Execulux) amp. Amp was built by Mark Baier with the remaining Gretsch Executive chasis he had.While playing, I hit a few notes and chords with emphasis and the amp distorted in a not so good way. Seemed to mostly react this way to notes played on the B string on a couple of different guitars. I started checking a few things out, like making sure jacks were clean, tubes were seated and not microphonic. Problem continued for another couple of minutes, and then as if someone flipped a switch, the amp just started working normally and sounding like it should. Any ideas?
