Hmmm,
Tom, SURE you already know this but John Sykes is Mr.Cold Sweat.
AKA, the BKP's, although Emeralds would be more "classic" Lizzy.
In later Lizzy years (post REAL Lizzy, i.e. after Phil passed) Scott was using Marshall SL-X amps, no pedals, just amp dist.
He has used various Marshall SL's too.
