... for the suggestions - much appreciated!
I went with the Tascam MKII and am quite happy with it so far. Got the power supply too...
It's a great little unit.
After playing with it for a few days, I decided to run the Tascam line-out into my cafe walter headphone amp & plug my bass guitar and headphones into the cafe walter, using the Tascam mainly as a CD player/looper - and I've been extra-happy with that as the cafe walter seems to have much better bass guitar sound/tone than the Tascam (JMHO).
(If I want to fiddle around with the effects on the Tascam, I can always go direct to that.)
I just knew TB was the right place to come for ideas & assistance!
edit: p.s. - the instruction booklet for the MKII is as poorly written & organized as anything I have ever seen - too bad, as the product itself is quite nice.
