Title: The power adapter is good - the equipment isn't
Review: I bought this power source to be used with the Tascam CD-VT1 vocal trainer. This adapter works fine, but the vocal trainer didn't remove vocals as promised nor did it change tempo or key of the song (on a CD) without seriously warping the sound. If that is the purpose for buying this power source, don't even bother. I understand from other reviews that the guitar trainer is pretty good, though.
Is the review positive or negative?
