If you don't want to take a whole pedalboard worth of gear with you, this is a great product. It fits nicely in my bass' hard case and I have it set up with a few of my favourite presets such as a chain of compressor/limiter and EQ. For live work I could see it as a bit of a fiddle to reliably and quickly switch between presets - there is a feature that allows you to do this, but you have to be looking down at the little LCD screen to check what's going on. The in-built tuner is perfectly OK, not a Boss TU-3, but OK. If you factor in the price, the form factor, the LCD screen, the battery life on a pair of AA batteries, the build quality (metal body) and the sound quality this is a winner, despite its inherent fiddly-ness. It would be totally awesome if it had a MIDI interface that could go to some foot switch board for selecting presets - then it would get 6 stars.
