I'm sure you will find good use for it...I have used a couple of different wedges for the same purpose/idea. I have played dozens of gigs bringing just a guitar, preamp/modeler and an active wedge. I had a 100w one which even had tone controls - a pair actually, made by Solton I think, and a very small mtb? one later on. I built all kinds of bastardizations from them too, like an active 4x10 and whatnot. With bass I didn't even use a preamp, just plugged to the wedge and ran a line feom there to the soundman.
I ended up ripping the tweeter out though...it was always all too bright and piercing even with eq. And cutting treble heavily would make it just murky...but tweeter out of commision and then added treble worked real nice.
They don't really give an amp feel, imo...they're great on gigs with PA taking care of foh sound, and for home practice, but normal band playing, well it's nlt gonna give the punch and bite of a real amp. But I don't think you even expect such :-)
