So I'm getting rid of my Peaveys(410TVX and 115BXBW) over summer and buying an 8x10. I was originally going to get a Mesa but after playing one and seeing the price tag they aren't worth it. The Megoliath was nice but wasn't present enough in the mix to keep up with the detuned guitars, leaving me with the choice of Peavey, Ampeg, EBS or GK. I'd love an EBS 8x10 but they're mega expensive, I'd like an upgrade from Peavey, Ampeg are OK but I'd like something a bit more articulate, which leads me to GK. The 810SBX is fairly inexpensive(slightly cheaper than an SVT810E), and seems to compete very well with the Ampeg on paper(sealed cab, bigger range of frequrency response), but I can't find any reviews on it anywhere. What I'm after is punch and definition with a little bottom end, not too much(tune to Bb) and some nice growl, an aggressive tone where needed. I use bass distortion and a slew of other FX which are pretty clear through my Peaveys, and I guess with the GK ethos they'd be as good(probably better) through the SBX. I'll be hitting it with a PSA-1 preamp and a bridged QSC RMX1450, and a couple of Spectors.
