I sold mine off quite a while ago, it was OK though,
a compact amp/effects box with just the right features.
But to my ear, it probably has a cheaper or under powered CPU compared to the more up market Boss stuff,
as there was a slight 'grainy'ness to the sound, but you wouldn't notice in a band surrounding.
Also as with most compact pedals, patch selection is up/down, with the usual foot tapping to reach the next patch 2 digit number.
I would not waste batteries in it, they don't last long, OK if you have shares in 'Duracell',
but it works with a regular 9 volt DC adapter.
A lot of bang for your bucks.. you would pay the same for a single function analog pedal.
