This is the greatest pedal I have ever used. It made my delay and distortion pedals I was using obsolete. So what exactly does this pedal/processor do? Well, many-a-thing!
It has 8 distortions (well, 7... they include the acoustic sound as one), all of great sound quality. It has an amp simulator, Flanger, Phase shift, delays, pitch shifts, doubling, chorus, reverbs, and gain and sound output levels. It has an auto-chromatic tuner which you can play with or without sound coming out (the tuner uses the lights on the pedal). This pedal has it all... it's the best.
This pedal has 24 preset sounds. You can mix and make your own sound by varying the sounds of distoritions, gains, chorus, flanger, reverb, etc. to your own preferences. Each sound channel is called a patch. The patch lables on the pedal are A 1-4, B1-4.... all the way up to F 1-4 making 24 sets. You can have anything from the heaviest distorion, to the smoothest clean guitar you've ever heard.
I got this pedal from Musician's Friend, a magazine which has guaranteed lowest prices... I like it... it's free! To go there, go to this page's link section. If you have any detailed questions about this pedal, email me. Just go to the email icon on the main page.
