its wonderfull, I am playing with less and less gain as the vintage channel is just so responsive, the sustain is like its on a button for some guitars ...its a brilliant tool for testing different sounding guitars, it enhances the character of each guitar ...if u know what i mean....and its so so loud...for the first week I had to go round tuning my studio to stop all the vibrations in the radiators, cabinets, etc..lol every possible thing that could vibrate was strapped down....i love it and I am recording and playing a lot more ...but thats also cos me house is finished and the studio finished, and i am settling for the winter...lol....
