This is the combo I'm looking at getting within the next month (all ready have the GK and a have a line on the 610). I'd be replacing my Ampeg 610 with the Bergantino. Is anyone out there using this setup? I know the NV610 loves tube amps (and I've had plenty, probably with more to come in the future), but how will it respond to the GK growl and punch that I love so? The GAS voices in my head say that GK + Bergantino + Rickenbacker == best tone ever. Can I trust them?
