Worst case scenario you should be able to hook up the jb3 to your line in on your computer via 1/8th -1/8th and play it into something like Soundforge. I know it adds a generation of analog to the process, and it is a real time 1x transfer, but since the tape wasnt pristine in the first place it should sound fine. Certinally not the propper way to do a transfer, but it will get the music onto your hard drive so you can start working with it.
