"I recently purchased the ART Tube MP [...]. My primary purpose was to input my bass signal to my PC sound card for recording. I instantly got the rich, warm, deep, fat sound that I have been seeking. I play reggae dub (classic Sly & Robbie style), after 5 minutes of playing I knew this hidden jem was the piece I've been missing. As a DI for a bass I highly recommend it, the ART tube MP gives me the EXACT sound I want. If you want a truly awesome dub sound, without the ""bells & whistles"" this is all you need. eDub Indianapolis"
