I recently stumbled across this on amazon, and bought myself a Christmas present. It's basically a CD player, with bass input and headphone jacks. I've got Play-along CDs and tab books for Hendrix, Led Zep and the Who. So far, so good. I'm able to get the levels and mix just right, and navigation is easy. I can also slow the tempo without changing pitch, or vice-versa. It enables me to practice at home without annoying the wife, and sharpen up my skills considerably. Good price, too. Waddayall think?
