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

Which crystal the DSP one or the Zilog? I would leave them, the 10 
MHz Zilog models have a 20 MHz crystal (they divide by 2 internally). 
There are also timer and interrupt issues that are in the firmware, 
so if it aint broke don't fix it! Absolutely DO NOT change the DSP 
crystal speed!

Only the older Zilog mcu can be upgraded to higher speed, but also 
involves a firmware change (to adjust for timers and etc having a 
different clock speed)

Just my 2 cents since I do embedded work for a living.
