G&L Legacy, SSS to HSS conversion wiring question

Post by josephgriffiths »

Hi all,

New to this forum. I've done lots of researching and searching here and found one diagram but need some help. I've just yesterday taken out the Bridge single coil on my SSS G&L Legacy and put in a Seymour Duncan SH-5 humbucker. I've done a like for like swap out, so I'm not trying to do coil splitting or anything. I just want to have a HB on my bridge and it works for the most part, (noting i had to swap the wires around to keep the polarity in line with my middle PU).

THE ISSUE is the 250k Volume pot, basically it sounds far too dark. I know I CAN'T put a 250k resistor in series.
My QUESTION is how are normal HSS legacies wired to balance the pickups?

For example - I see on Fender strats they typically use a 500k volume pot then put 500ohm resistors in parallel with the neck and middle single coil pickups. but I'm not sure if this will work for a G&L as it has the 500k treble and 1M cut knob. or am i overthinking this?

There is a diagram on this site that includes a push-pull to split the bridge PU but doesn't have any additional resistors to allow the highs to come through. I don't want to split anyway.

One thought I had was that as I dont really use the Bass vut anyway I could rewire the whole guitar to be more like a Fender HSS for which there are many diagrams online.
My second idea was to get rid of the bass cut and have two volume controls so a 250k and a 500k for the bridge, which seems like a simple solution

Advice (or a diagram) would be most appreaciated! Thanks in advance

Hey there,

I went over my notes for my Legacy HB mahogany and noted down this for its wiring harness:

"CTS 250kΩ Audio Taper (R137) volume pot with a 200pF (201K) ceramic treble bleed cap, treble cut using a CGE 500kΩ Audio Taper (D500) pot in series with a 22,000pF±5% (223J100V) to ground, bass cut control using CGE 1MΩ Reverse Audio Taper (1M) with a 2,200pF±5% (222J100V) treble bleed cap"

Here an image:

That should be a good starting point.
