Hi, I just purchassed a used gsp-2101 from digitech, everything works fine exept for one thing, it's SO NOISY! sounds like if there was a train behind. It has 2x 12ax7... I was wondering if it could be those who were getting old....If not, what else could it be ?? I verified, it's not my guitar, my cables, my amp...nothing, it's realy in the processor. I noticed...there's a wet-dry fader, the more wet it is, the more it's makes noise.
Thanks
