Got one of these recently and have been trying it out. I got it because I wanted to give my fretless a haunting distant sound. It works pretty well for that, but I was suprised to find that it works best on my baritone guitar. I was playing some of the lines from Tiger Army "Outlaw Heart," a sort of spoof of an old western swing song, and the reverb made the baritone sound awesome. I have to work with the pedal more, but my only complaint is that it can compress the sound of one's bass even when off. I would recommend the pedal though. Has anyone else have one of these and what do you think?
