I have a PowerCab + that I got a month or so ago when they first came out. It works beautifully. I run my BE-50 through it via my UA OX. The trick with any FRFR is to turn off that compression driver (aka the tweeter) when using high gain at a louder volume. It really compresses and squeezes the tone too much and sounds odd. With the PC+, you just select FRFR flat and that turns it off. Works and sounds great. When playing live, I use it as my monitor from the right out of the UA OX. The left out goes direct to the PA system.
