Yes. Mick used a 200 watt Marshall Major. This version of a Major was different to Ritchie Blackmore's Marshall Major. The "Pig" major had 3 knobs: Vol ,Treble and Bass. Live- the vol was cranked to full. This is why the two outer KT88 valves were removed. The Marshall Major Pig was mindblowingly loud amp!
Micks fuzz was Tonebender mk1 fuzz. Wah wah- vox was early days ,Jen crybaby later on.
Mick also used a Marshall cab. David used the Simms watts amp . After the first American tour Mick switched his celestions to JBLs, likely as they handled the Pig more efficiently . Mick's sound became brighter with the JBLs.
Micks main guitar was a 1968 les Paul. It's pickup likely a mid period 1960s paf humbucker. (yes t tops did also appear on some 68s)
I'm fortunate to be friends with Robin Mayhew (Bowies sound guy during the Ziggy era) and I've also been lucky enough to play with some of Micks former band mates in Hull.
Ched the bass player from the Micks early band The Rats has also been a great source of info. David Main (D*A*M) and I also spent a great deal of time in the mid 90s trying to work out the fuzz Mick used from photos. Ched also confirmed it was a MK1.
At some stage in future I will release profiles of my Marshall Major Pigs and Vampower amps- once im completely happy with the profiles.
Hope this info helps .
