Great sound but just way too noisy.
Pros: Built quality, sound, connectivity Cons: NOIIIISSSSSSSE! All over the place. Had to send it back :-( I'm now using the Moog Multimode Filter XL on the UAD wih the Softube Console1 to control it hands-on. Sounds not as good but at least it's not noisy - good enough for me as a home studio guy. And if I want a tiny bit of analog noise, I send the signal through my KT-76 Urei clone for some "analogueness".
