That being said, I think the guitar plays a large part in this as well. I had my Marshallhead in a Gibson SG 61 Reissue, and it sounded flubby and dull no matter what I did. Switched it over to my LP traditional, Boom. All the punch and chime was there. No matter what pickup I put in that Sg, it just had a soft mellow sound that didn't jive with me.
