"Yeah, I just use Marshall STOCK heads. There's nothing really special about them. (I like) the brightness and punch. I didn't use Marshall all the time. They made some cabinets for me; better than the cabinets I had and they sounded great. We asked them if they would send me some heads and they sent me the heads. My brother dialed in the tones that I like. This is what I got" - Tom Araya
