Hello everyone, I was wondering if anyone has any experience with sending an amp back to sweet water for repair? I got my dream rig last year, an ampeg heritage cl with the heritage 8x10 and I’m having issues unfortunately. It buzzes and crackles violently when hitting certain notes or pushing any kind of volume through it. I’m pretty sure it has something to do with the control board because I can tap the wires with a chop stick and it will do it. Also I can bypass the preamp with my le bass and I have no issues. Any insight on the process would be greatly appreciated. Sorry if I posted this in the wrong sub.
