I came up with an interesting mod to the 4-way Tele wiring I posted previously. I’m really a big fan of the 4-way switch option. Maybe 4 is my magic number and 5 is just to complicated for me, I don’t know.
Anyway, what I’ve done here is take the Custom 4-Way wiring and add a Master Bass Roll Off, similar to what I put in the 4-way Strat wiring. This type of bass control comes from the G&L Legacy. I would recommend using dual stacked pots. Unfortunately, I don’t think you’re going to find a 250k/1MC pot, but you can definitely find dual 250k as well as 250k/500k. I haven’t evaluated how awkward or inconvenient it might be to stack the tone with the volume, leaving the bass by itself, but it’s here for your information. You can always drop the bass control by shorting out its connections.
As shown, the wiring is humbucking in all positions,
- Full Bridge Humbucker
- Half Bridge/Half Neck in Parallel
- Full Neck Humbucker with extra bass roll off (C3)
- Half Bridge/Half Neck in Series
The 2nd thing I’ve done is to replace the bridge-activated tone control with a fixed “sweet spot” tone roll off that is paired with a traditional tone control. What this does is allow for some extra roll off when using the bridge position, but also let the master tone do its thang. C4 is the fixed “sweet” cap and will usually be a smaller value than C1. You’ll have to experiment for find the right setting for you. R2 should be 1M Ω.
I’ve also left on the 500kA Volume pot. This will brighten the guitar in all positions, giving the tone switch and control more signal on which to work the magic. Last but not least, I’ve added 2 coils to the setup, representing the additional options when using humbucking pickups in the neck and bridge. Shorting L2 and L4 will return the diagram to the 4-way single coil wiring.
