Bought this to run straight into mixing desk for small gigs.
The clean sound is really bad, and very compressed. No matter what i did, i could not get a decent sound from it. (Ran into 2 x RCF J8s, and also Victory Duchess - same result...clean sound was terrible).
The crunch and heavy channels are fantastic, and very easy to get a sound from, and the XLR out is very useful. Pity it doesn't have reverb. It will give you everything from a country crunch to Slayer! I found it great for an AC/DC type sound.
Over all, i would give a 7/10. Easy to use and ideal as a back up, but the clean channel really lets it down.
