Nice one !
It was very interesting to hear how the Riff Raffs put their characteristic edge and bite on the notes in this context.
For my personal preference, I still prefer the rounder tones of the Stormy Monday or Mississipi Queens in a 335 type guitar - but the Riff Raffs certainly provide a very valid alternative to the smoother B.K.P pickups a 335. I presume that they may be closer ( than the S.Ms & M.Qs ) to the Gibson '57 Classics in character ?
