Since I already have a PODxt, what about using the Tech 21 Power Engine 60 1x12 combo. Since it produces a flat signal and isn't supposed to color the sound any. It would also be cool to A/B the PODxt and power engine with my Peavey Triple XXX head and marshall cab. The possabilities would be endless then.....Any opinions on that setup (not the XXX, just the PODxt and the Power Engine)?
