Another player worth checking out is/was Pete Laity from Coventry. Very popular on the folkscene of the 80s/90s, Pete made a couple of LPs which demonstrated his truly virtuoso ability, albeit influenced by Gordon Giltrap (another whizz 12 stringer). Pete played a hand-made Rob Armstrong.
Nowadays, he tends to prefer making a lot of noise on a Fender Telecaster in the Aardvark Ceildh Band, and rarely plays the 12 string. Shame!
