I was happily playing my american standard precision funking along to some RATM when my 1001rb started sounding really muddy and just buzzing and flapping..... this was a new sound for me. at first I thought it was my speakers going, as i carried on playing it just got worse and worse, with each pluck there was less of the note and more of the buzzy flapping sound. I tried changing cabinets but it was still present! this is when I started to panic. I turned it off for a few minutes and tried it again. it sounded more like a bass this time, but without the bass, the buzz was gone but now it sounds really awfull, kinda like when your battery is going on an active bass (my bass is passive) and the buzz is still there when hitting the low e, but not as bad. does ANYYYONE know what this could be? I have no idea about amp electronics iv tried email GK but my emails cant seem to get through.
