I agree. If you use bargain bin tapes, you are taking your chances with not only sound quality, but really clogging your heads. And do you want the little circle this thing's suction cup is going to leave on your machine?MadAudio said:Feh. A waste of money, IMO. It reminds me of a little of the tape cleaners that were on the cassette loop bin units where I used to work, but since they were using really cheap tape stock it was a necessity. For good tape on a pro deck it's really not necessary.
