The Swamp DB-1 works well with my Classical Electric Guitar. I turn up the volume of the Fishman pickup to maximum and plug into the XLR input on whichever PA I am using. There is no noise and the the output is such that the channel is neither over or under driven. If I am using an active, battery powered guitar pickup I will first try using the Swamp DB-1 when sorting out the guitar sound before gigging.

All you need in a DI at a price that's hard to beat. I'm using this in a bass guitar rack. Sound quality seems fine, though I don't have anything really high-end to compare it to, and high frequency definition isn't so critical for bass guitar. There are also some mounting screw holes that can just be seen in the photographs that were useful for mounting it inside the rack box.
