My first choice would be me, because I've been playing them for 40 years 🙂
But I'm not an official endorsee.
So my choice is Noel Redding because:
His playing was an essential part of the sound of the Jimi Hendrix Experience.
and
I once peed in the same trough as him during the interval of one of his gigs at De Barra's Folk Club in the early 90s.
