Have had this for a while. Struggled a little with it being noisy, but recently figured out you need to run it at a healthy gain level - if the gain is too low on the unit, noise seems to be added. Have it running clean now, and it sounds fantastic.
EQ is great - very responsive. Low and High only, which is limiting, but it's so dynamic you can deal with that. The FX loop, which is the primary reason for buying it, is wonderful - I'm running a distortion, POG nano, delay and TC HOF2 - and the mix of sounds and quality is brilliant - most of the time it's just the reverb, and it's a new world in terms of sound quality and control compared to anything else I've ever used.
Only thing that still bugs me and that I haven't managed to work out is the level difference from the FX being on and off. Unless you overload the input and receive levels, when it starts being uncontrollable in terms of the FX volume, it's far louder without the FX loop on. You can of course just turn all your FX pedals off, but it doesn't sounds as good as when the FX loop is off. Minor glitch that is work-around-able and other than that, a brilliant unit.
