I couldn't find one thread about the Superscope line of products...anybody else use them? I recently bought the PSD300 which has 2 CD drives, allowing you to change tempo +/- 33% (without changing pitch), change key up to an octave, record direct to CD with a play along, etc.. I guess there are some software applications that serve some of these functions, but this unit is small and light weight, functioning as a pretty good live to two track recorder direct to CD, with the ability to burn a CD for the band before you split. I am finding this to be a great tool that I wish I had 20 years ago. I can finally hang with Rocco (well, if he would just slow down a little). Any comments, tips, questions? Hand slappin' for telling me about the product(s) I could have bought that are better at half the price? I can take it.
