http://www.tascam.com/Products/cdbt1mkii.html Just wondering if anyone has seen or been able to use these yet...I know they're still relatively new on the market. Along with being able to slow down music for transcription, this one supposedly also boosts the bass to hear it better, as well as cuts it so one could play along with the recording. There's also a guitar and vocal/wind instrument one, not that those matter . Plus it looks as if though they're less expensive than the Superscope CD Trainers. Looks like a great tool for bassists...or any musician I suppose... Any thoughts?
