Wow as a proud owner of much Marshall gear I give my heart felt condolences to the Marshall Family.
He was a true visionary of the sonic tapestry of Rock-N-Roll. Thank you Jim for your great contributions to the musical world of heavy metal, blues, etc.
I have yet to own a Marshall amp, even though almost every guitarist I consider an influence on my style (or that I ever stole a lick from) used Marshalls at least occasionally. My rig is a Fender Hot Rod Deluxe, and while I lament the fact that it doesn’t do that thick, crunchy distortion of a good Marshall amp, there ain’t a Marshall in existence that can match its clean tone (oddly, that was what sold me on the HRD, even though I don’t play clean very often).
As a point of interest, Jim Marshall’s very first amp was in most respects a copy of a ‘59 Fender Bassman. The difference in tone came from the differences in his components versus those that Fender used.
