It's interesting to think that the Marshall sound I helped Jim and his guys develop was built around the very low output and thin, surfy sound of the Rick. The sound I wanted was Steve Cropper, but very loud. The early Marshall with a Rick gave me that. The semi-acoustic body and a speaker stack feeding right into the guitar was what allowed me to refine tuneful feedback.
