I have a couple of 212 cabs sitting around not being used. Sell the cabs? Hell no. Buy more amps. I have clean and classic marshall covered in spades with a Roland JC40, a Fargen miniplex combo, and a Friedman Smallbox. I don't have really high gainers. Was looking at the two small heads in the title. I know which way I'm leaning but I am unable buy a pick without asking a forum for their opinion. Metallica is about as heavy a music as I ever play so keep that in mind.
