Tech 21 DP-3X, yes the DUG pedal everyone raves about. My favorite pre-amp that Tech 21 has made. Nails Kings X tones, but I used it for a harder edged blues rock band. It crushed. Hate to let it go, but I can buy another one down the road. I do not have a power supply, but can let you use one to test it out if needed. I had Mike Putnum (Putnum Gutairs) add 3.5mm input for MP3 players, but it didn't work as well as I had hoped. Music comes across low volume in headphones
