dude, I have a jam man and it is awesome...I have got the 2gb flashcard and can record and loop up to 6 and a half hours...and I can overdub and everything...you can also change the tempo of the loops with the tap tempo footswitch,so if you drummer starts the song too fast/slow...just tap along in time before hitting the loop...change the tempo, but not the pitch...this thing is amazing...even with the supplied memory card you have 25 minutes recording time...I cant believe I played guitar for so many years without one
