Still have a sort of love-hate with my Laney GH50L. Sounds great but it's very "dry" and hard to play for lack of a better description. Just seems to fight against you somehow haha. I want to try out a V30 cab with it as well since I'm still not sure on the G12H30s, bit fizzy which I think is the speaker breakup.
yeah it probably is partly the speakers. it's a bit gritty rather than smooth anyway, but g12h30s sort of accentuate that. I actually like mine with (heritage) g12h30s but it did take me a while to get used to it. It's definitely smoother and more modern-sounding with v30s... but also a little generic, maybe. I prefer it with more vintage celestiony style speakers (which is not to say you necessarily will, of course).
I didn't really get on with the genz benz el diablo. I really liked it when i tried one ages back in a shop, but then i picked one up recently from gak when they were blowing them out... just didn't "feel" right (I found out just before it arrived that it's not all-tube, which may have skewed my perception of it, but still...). the more i used it the more i was starting to like it, though- it was a bit tricky to dial in, it's quite complex. But then the thing died on me and rather than get another one and maybe still decide i didn't like it, i took that as a sign and just took a refund :lol: GAK was very good to deal with, fwiw.
