I recorded some Commander Cody on one of them warmalt tapes this evening, and the results are pretty good. I have no dropouts, the levels on both channels match, it biased up just fine, with the peaks being at +7db. There is a teensy bit of hiss heard between tracks, and its not quite as transparent as a good chrome or metal, but hell it cost $2! I recorded it with my Nakamichi BX-300 (3(crystalloy) head, dual capstan, direct drive, pad lifter, A.N.T. mods) and am listening on my Sony TC-K71 (3 head (sendust+ferrite) dual capstan)
