Well, I managed a five minute fiddle with one of these this week thanks to the kind people at PMT Leeds.
The look and feel of the unit was high-quality, a solid little lump with a lovely machined front.
Plugged into an Ashdown Neo 15 it sounded pretty good with everything set flat and it was very easy to adjust the sound with the graphic.
I would have really liked more time with it, but lunch beckoned.
I'd certainly be interested in trying one with a band using my own bass and pedal.
