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

Has anyone been able to program a decent harmonized patch?   You 
know skynyrd or allman brothers type sounds in a 1 guitar band ;)

Is it possible or do I need to look for one of the DHP products the 
33 (3 part) or the 55 (5 part) or look into an even higher priced 
eventide?

Thanks
