I use it to add some character to the front end of my Traynor DB200 combo. Actuallly I just plug into the effects return unless I need more volume, then into the padded input with everthing set flat. I just use the first 3 patches. One based on the Eden Traveler, two based on the Portaflex, and three based on the SVT. I have not really delved into the effects much. The rest of the presets are pretty over the top save for one synth patch I can find some use for. It's a nice unit at a nice price and works for my application. Kudos!
