I've used a Mesa 2/50, Mesa 2:90, Marshall El34 100/100 and a VHT 2/50/2. I am currently using the VHT with KT77 power tubes and it is by far my favorite. They all had their thing that they did well but the VHT by far the happiest with all the modules I run. I go for a very Les Paul into Marshall vibe and my modules have all been modded by Pete Turley. I have a Top Boost, Plexi, Brown and XTC. I also just got a KH3 that sounds much more Marshally than I would have thought.
