I think we may have discussed this before... But, I had an older ES-340 with the 3 way (in-phase/out-of-phase/kill), Master Volume, Blend and two Tones. I really loved this scheme and would love to replicate it, but as I recall the switch had a couple extra blades for the poles. Love to figure out how to do this and still get the switch in a regular LP switch cavity. Maybe some day soon I'll start fiddling with it again. George, I will definitely be interested in your take on the GFS P-90s!
