Back to Mox - I'm sure that he performed with an R & B band (1964 British R & B) called the Taverners Guild, who always remained in my memory because the lead guitarist played a Harmony solid guitar which I think our rhythm guitarist bought from him, and used a Selmer Selectortone amp - the one 15" speaker variety, which although was only 20 watts or so was very loud indeed.

I had one of those which a friend of mine modified to be as loud as a Vox AC 30 when used with 2 Celestion Blue speakers (still in my attic).
