Clones are made with a Tascam Dual 302. Don't worry, I don't high speed dub. If you want 2 60s to a 90, clones are made from the Tascam to a Sony D8. As far as i know, internaly the Tascam Dual 302 only dubs. I use Sony and Maxell DDS medias. Normal trading rules apply. Please do not trade me used tapes or send used tapes on a b+p. Thank-You.
