ditto on the jb3.
i come out of all my boards (soundcraft, a&h, midas) and run directly into the jb3 line in.
i mix everything from corporate events to 108db rock shows. best bet is to use a pair of aux sends or the matrix to set up a dedicated stereo tape mix. just carry some adapters to get down to the effin 1/8th" input.
only downfall to the jb3 is that it looks like a POS consumer walkman, not like a piece of pro gear...and that effin' 1/8" input!
