I picked up a Zoom 4n recorder the other day and it is the coolest little toy! Well, not really a toy, but a surprisingly well-feaatured recorder/mixer in a tiny portable package.
Four track recording and the sound quality is unreal. I'm still learning how to use the darn thing, it's only got a couple thousand features and I know squat about recording, etc. But, I did figure out how to record my basses directly into it via the 1/4" jack, so when I figure out the next step (exporting the files to my computer) I'll post some clips of my builds. Very cool!
