I like it. I've used it. I'll probably keep on using it as long as our Front Of House guy digs it. The Californian is cool too. I should add that you'll hear a little bit of reverb plate in the mix. This is courtesy of IK Multimedia's CSR Plate plug-in. The interface I used was an M-Audio ProFire 610. They're inexpensive but sound pretty good. :)
If you have a scout around my channel you'll find demos of the other Tech 21 Character Series pedals, with and without amps and other pedals.
