Sound — 9
I use it with acoustic guitar. Recorded sound is clean, even with several overdubs. It does what it's supposed to very well and keeps everything 'live'. The built in percussion is OK but has some odd naff sounds. I find to use it well needs forethought and orchestration because only last overdub can be erased on the fly and results can get too cluttered, but they can be exciting.
Overall Impression — 9
This is a great match for solo acoustic playing. You can tap a rhythm, add a base line and chords, motifs and riff on top. It's got a mic input so can even add harmony but I haven't tried it yet. Now there's units with longer time on memory cards so it's price has dropped to 150. Not confident to gig with it yet but can see it being an indespencible part of set. Started playing in 1956. You work it out.

Rugged so long as you don't tread on the knobs.

What the manual doesn't say. The base recorded loop defines the loop so you must stop and start it on the beat (it has 'auto' feature but personally I've gone off using them). But the overdubs can begin and end anytime and will be added to the loop as it goes around. So start it after you're synced in to the beat and stop when you hear the start sounding. Or keep it going, record silence a while and add another riff, then stop. Sorry if this is obvious to everyone else but I struggled at first trying to press pedal at 'right' time when it's not necessary. Also pressing both pedals erases all.
