BS I'm afraid, none of them are copies of BBs............ours are all handwound with 42 AWG plain enamel, offset coils and unpolished Alnico IV magnets(V in the Riff Raff).........also they're all voiced by ear.
The Stormy Monday and Mule represent my versions of the original PAF(57 through to 60).......as is well known these varied greatly but I've gone for what I consider to be the sweet spots........Stormy Monday is the lower wound, more open version, The Mule the hotter, punchier version.The Riff Raff represents the cross over to a more symmetrical wind and Alnico V magnets.
