Well thats what I did last Sat. In my "big" band Sugartrain-8 piece old school soul/funk etc... Took it coz the gig was up 2 flights of stairs etc.. Was preparing for it to be not punchy at higher levels etc... BUT IT ROCKED!!!!!! Hope it's just a case of using something different-"grass is Greener" type thang But it handled the volume EASILY - was at 4 ohms thru the AGuilar GS112 & GS115. Sounded great- had the 2 filters about 9oclock each . Not QUITE as much solidity in the lower registers as the V4BH or SVT2 but still nice & even thu-out the freqs, plenty powerful(wasn't going thru FOH PA) . This was the 1st time I'd used it at a large-ish gig with this band- I always use it for our Jazz & blues quartet tho- SO I will try it again asap & post my results, but if it turns out to be so good for a long time...so I get used to it & then see how it 'feels'.... it's gonna be hard to justify taking an extra 40-70lbs to each gig!! I always knew it was a great li'l amp, but I'm SURE it was a case of - having a "New" amp there & a different sound- it happened a few yrs ago when I got my 1st S.A. amp too- lasted about 8 months B4 I wanted my old Power tubes back again. We'll see!!!!!
