jlf599 Posted August 19, 2021 Share Posted August 19, 2021 (edited) Greetings, I'm trying to rewire an older Steinberger GM5 (EMG 81 humbucker and SA single to a 3 way on-on-on 6 pole switch to a Hazlab). I'd like to try to verify the wiring and can't find any resources on line. It looks like I use the white wires to the switch, black from humbucker and single go to black on Hazlab, red on humbucker and single to red on Hazlab. For the white wires, I think it's: White from SA to pin 1 of the switch, jumper that to pin 2. White from pin one of the 81 to pin 5, jumper that to pin 6. White from Hazlab to pin 3, jumper to pin 4. The switch is similar to this one:https://www.allparts.com/collections/switches/products/ep-0080-on-on-on-mini-switch?variant=18579819921465 (pic of the actual switch attached). It's an on-on-on switch. It may actually BE that switch from AllParts, though I got it via HeadlessUSA. Does that sound correct? Thanks!

Be.eM Posted August 20, 2021 Share Posted August 20, 2021 Jeremy, maybe you're thinking to complicated. If this is an on-on-on switch you won't need any jumpers on the switch. Here you can see the wiring of a GM4 with a HazLabs board, which is correct for your guitar too, except the 5-way switch which is your toggle switch instead. On this toggle switch, simply solder the white wires like this: Neck PU: top left HazLabs input: middle left Bridge PU: bottom left The right side of the switch remains unused.
