Just modded a GCB95 I got for way cheap with just a few bucks in parts to do the mods. The reasons i did these mods is probably familiar to many ppl. The heel down had lack of presence, toe down was really shrill. To me this made adjusting the pinion not a great solution, as i wanted as much use of the physical treadle movement i could get. I thought I'd share my experience since I haven't found much info on the "Cantrell" mod and the pleasant sounds this made for me!
The Cantrell SIG has a 5k pot as a variabl resistor between the sweep pot and ground that limits the toe down frequency, it really tames the shrill without having to move the pinion to a lower sweep. I used a 10k with a rotary SPDT switch at the 0ohm position.
I used the rotary switch to add an additional .01uf cap to the existing sweep cap(also .01uf) for more of a Wylde sweep.
I also did the 2.2k "mid" mod which really helped the presence of the heel down tone.
These are all really simple to do and easy to reverse if need be, but the tonal diversity with this set up is worth the trouble. Hope this helps some folks out there!
