I'm not sure my Framus cab (front-loaded greenies) are meshing well with it.....the lower notes are getting a little mushy when I play decently quick. Kinda like there is a little to much "give".
Same here, VERY punchy with my VH4... There's a guy on youtube, plays a ton of Tool songs with Herbert and Mesa Cab. Check him out - http://www.youtube.com/profile?user=opiateofthemasses
