Hello, I wanted to reach out and just see if anyone could offer some advice. I have a fender blues deluxe re issue. After about an hour of playing it starts breaking up terrible when I hit low notes. I have to turn the bass all the way down to one to get it to quit. I just re tubed it and replaced the speaker with an eminence swamp thing about 9 months ago. Any advice on what to check? I really appreciate it.
