yes mostly - but if there is not enough gain i combine the two preamps.
i use the setup for recording, the amps are just to say "very fine stuff"
wasn't disappointed with the sounds available by now. though the internal fan is a bit too noisy.
someone asked here for recording amps, for me the Ace is definetely the one.
live i use them both by running just one preamp, mastering the effects and stereo back into the main amps. thats ok, loud enough anyway ;-)
listen to it - but when you crank 'em you are lost and you will pay the bill for it
enjoy!
