John Frusciante’s Boss PSM-5 Power Supply and Master Switchaccess_time First seen circa 2002
John used this pedal briefly during the By the Way tour. According to his tech, Dave Lee, the pedal was used to activate three distortion pedals at once.
It was used to turn on distortion pedals at the same time. I believe three different pedals. It was also used as a power source for some pedals. At least that’s what I remember.Dave Mail 115: PSM-5, CE-1, MF-103, and Fuzzrite
It would be interesting to find out why exactly John felt the need to use three distortions at once – so if you have any idea or happen to remember him using them (for instance at Slane) leave a comment below.
