It is my Peavey T-Max 210 Combo.. Great amp, until last night. And I hope it is nothing big... I was playing and my guitarist asked if something was "buzzing".. I thought it was fret buzz (my Ibanez needs a set up)... Then I moved and heard this "rattle/buzz" when I attacked the lower strings. Very noticable on say the 7th to 8th fret on the E string... The strange thing, was when I turned on my phaser and flanger, there was no rattle/buzz.. Once I turned them off - I got that sound again.. At lower volumes, and even on the D and G, it wasn't really there... I didn't see any tears in the speakers... But then again, I didn't have time to tear into the cabinet last evening.. They are the original speakers. Any help, insight, similar issues would be greatly appreciated.
