Its a preamp/FX rack from digitech, the 4 cable method is a way to hook it up without coloring your tone, it actually does color it but very little. I use it to the gate my amps, and to add delay to my lead channel. It has midi capabilities, and has a feature to bypass the preamp section of your amp and just use power and save it as a preset. in case you have an amp with no usable clean channel, you can create a preset using a nice clean jazz amp and chorus or whatever. Theyre cheap too, I got mine for 200 bucks.
Thanks man. Sounds pretty similiar to my Lexicon unit. Im might have to check one of those out
