I also play bass and guitar
At home I have an EV ZLX12P top with an EV ZXA1 sub. Sounds fabulous but would really like the Tech21 Deuce Deluxe for a grab-and-go (11R in one hand and the cab in the other), whatever I play bass or guitar. Probably also a nice match with my Ampeg SCR-DI bass preamp. 2 of them and we are rocking the house!!!
Looking at the specs, looks like the new Power Engine is based on the cab and power module from the VTBass 200 bass combo. So I imagine the Power Engine will be good for bass also.
