I had one for 2 yrs. and it is complete low grade stuff. Dude! Look at the people you named who are those bums? I reconized a few bum but cmon. Im talking aboout the best guitarist in the world. EVH,VAi,Petrucci,Lukather,satriani. tThe only thing that Digitech makes that is good is the whammy pedal. Back in the day when they came out with the dhp-55 and ips harmony machines those were pretty good but now. Go to huge racks web site and they have thousands of pictures of basically every pro's rack from the 80's until now. And you know what . No digitech. All you see is eventide,lexicon, t.c. yamaha. Oh yeah cant forget those old roland and korg delays they are truely top notch . I dont mean to be rude but I really really tried to get a good sound out of that box for 2 yrs. and at one point i thought i did. Then i joined a band with another guitarist who had a t.c. 2290 and a eventide Dsp 7000 and when i heard this guys tone compared to my totallyprocessed cheesey sound I unplugged the unit and pluged straight into my marshall. That guy really taught me alot about racks and stuff and told a few websites to browse on. What you should do is sell the digitech for about $300 and go on ebay and pick up a yamaha spx 90 for $200 . Thats if you are on a low budget.
