This conversation is about the amazing book Peter and Brian have put out which is basically THE handbook on Marshall Amps. These guys know more about Marshall Amps than anyone we have ever met. It's a wonderful coffee table style book with amazing pictures and so much knowledge. No stone is left unturned.

You can purchase the book from their website
