I had a (then VHT) FB cab with V30s and it slayed every other cab I owned. I got rolled when I bought it off CL, as the guy said it had the stock speakers, but it ended up having Sheffields. A buddy of mine just got a Peavey cab unloaded, and jumped on the Sheffields, and I dropped some Mesa V30s in it. That cab lived in my trailer and was on stage with me for every show I played for several years. In the end, I sold it to a buddy because I got sick of looking at it. It was beat to fuck and the wood was starting to splinter on it. Still the best sounding cab I've owned to date.
