I know there are several Mpluse 600 users here and a smaller handful of Venture players. I am working on doing a little rig updating (selling off some unused/less used gear) and looking hard at the Venture combo. I'm very happy with the combo format and and use a Walkabout 12 combo right now. It sounds great to me but maybe a bit headroom shy on my larger/louder/outdoor gigs. My thought is that the Venture would allow me a bit more headroom and a bit different tone pallet (i.e. per KJung, the 600 is NOT a bigger/louder Walkabout). So, I have the opportunity to pick up an older, discontinued (not used) Venture 2x10 for a very good price; or, I can grab a newer version 2x12 model perhaps at a small discount from Mesa list. Aside from the differences in the head (speakon's is about it I think) are there major differences in the 2x10 vs the 2x12. I'm guessing the 2x12 will be quite a bit louder, or at least it will project the Mpluse's 600w of power with a significantly "larger" sound. The difference in price at this point is not the biggest factor, but the ~$400 I might save going for the 2x10 is nothing to sneeze at either. What I'm looking for is feedback on the differences I can expect between these 2 versions of the Venture. FYI, I have played the 2x10 and it sounds very good, even to my not-in-love-with 10's ears. I would also maybe consider adding a PH1x15 to flush out the sound for certain settings. I Don't have a ready way to try out the 2x12 though, thats part of the problem I'm facing. so, any input ?
