My name is Jeff and have been using Dimarzios since the late 70s....among other things.
I mostly play hard rock on various PRS and Gibson guitars.  I have been doing all kinds of pickup and tone circuit experiments with a Gibson SG-Z that has a humbucker rout in the bridge and a single coil rout in the neck position.  The jury is still out....
I have ASEET and BSEMET degrees from PSU and have been doing music electronics since the late 70s as well.  I remember programming the entire synth track to The Who's "Baba O'Riley" on a Commodore 64, lol.  Started using MIDI backing tracks and guitar switching in 1985.  Was developing my own 4 channel guitar MIDI switcher until I found out that Tom Scholz already beat me to it.
