Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

Hi, does anyone know if the output chips on the 2101 affect the whole output, or just the XLR 
outs. I find that after a set of playing my 2101 Artist starts to sound a bit brittle and loses 
sustain and volume. i'm wondering if old output chips might be the problem.

Thanks,
alex
