Roger Mayer Roger Mayer also built fuzz pedals for Jimmy Page and Eric Clapton. “But the secret of my sound is largely the electronic genius of our tame boffin, who is known as Roger the Valve [Roger Mayer]. He has re-wired my guitars in a special way to produce an individual sound and he has made me a fantastic fuzz-tone, which you can hear to good effect on our new LP, ‘Axis: Bold As Love.’  Actually, it’s more of a sustain than a fuzz.  He got a special sound out of the guitar on ‘One Rainy Wish’ and ‘Little Miss Lover’.  It comes through a whole octave higher so that when playing the high notes, it sometimes sounds like a whistle or flute.”- JH New York January 1968   “I spent a lot of time with Jimi privately, hanging out and talking about the sounds and maybe bringing a few [fuzz]boxes around the flat so he cold jam in private. And we would get some general ideas of what we were trying to accomplish in the way of sustain and tone. We were normally using colours to describe the sound.” –Roger Mayer
