I've always liked the guitar sound of Allman Brothers Band especially the earlier stuff like Live at the Fillmore East and Brothers & Sisters. It used to be all over FM radio back then. Was talking with a bass-playing buddy the other day who dropped something of a bomb on me by telling me that Duane and Dickey put JBL speakers in their Marshall cabs? I immediately did like a head slap thing ;-) Doh! I had no idea. Guess I never really thought about it much but it sure explains what I would call that characteristic ABB guitar sound of that era. Cleans up the Marshall/Celestion grit and gets a more defined sound. I'm not a pro or have I ever owned a Marshall amp. Has anyone here tried using JBL's with a Marshall? Curious to what you think about that sound.
