Treble bleed wiring on LP.

Does it work with both 50's and modern wiring?

Id like to install two on my LP and was curious if the 50's style wiring that I presently have would still allow that mod?

Thanks y'all!

Its moot on 50s wiring, the point is to retain highs as you roll back the volume but with 50s wiring you dont have that issue. A bleed will only be beneficial on a modern wired harness, modern you loose alot of high end when you roll back that vol pot without a bleed circuit

I concur with Mookakian, but it technically does work even with 50s wiring. If you want more brightness as you turn down the volumes, you can do it. With everything on 10, 50s and modern wiring are effectively identical and the treble bleed is bypassed.
Both 50s and modern wiring schemes allow for interaction between volume and tone pots. If you want your volume pot to effect tone, go with modern wiring. If you want your tone pot to effect volume, go 50s. If you want to eliminate as much interaction as possible, go with the modern but with a well-tuned treble bleed. The values of the resistor and cap on the treble bleed network may have to be tweaked to fit your pot tapers and your ear.

Yep, i also find if you Have a few caps to try on the bleed, often the resistor isnt needed, if you like the taper of the vol as is its better to use the right cap value rather than tweak it with a resistor, but s9metimes the resistor works in your favour and changes the taper for the better

Band-Aid on a bullet wound.

A treble bleed is like stabbing your tires with a knife to get better traction. Sure, you will, but.... not the best way.

Personally, I'd try to address the issue at the source. If you don't have enough treble at the point of the volume pot, there's only ONE electrical component upstream of that.... a muddy pickup. Can't put back with electronics what was never there to begin with. You'll just let more "upper mids and lower treble" through along with phase cancellation or some other unnatural sounding artifacts.

If it's not the pickups and they sound fine wired straight to the jack, it's something else in your wiring that needs correcting / replacing.

Its not the pickups that cause loss of treble as You roll back the volume pot, its the nature of the circuit. If your tone has little treble regardless of the position of your volume pot id maybe agree but in this situation its definately not the pickups that cause the treble loss, we dont use a treble bleed or wire it up 50s style to fix a muddy pickup, we do it to stop highs getting taken out by the tone circuit as you turn your volume down.

The treble bleed is for those who dont like the interaction between the tone and volume pot using 50s style... so they wire it modern style so the position of the volume pot doesnt interfere with the way the tone dial works, and just want the tone dial to take out high end. And if you place the tone pot/cap on the 1st lug of the vol pot straight from the pickup hot, as you roll back volume the circuit will bleed high end, put a small cap across the lugs Of the volume pot and those highs stay in your tone so you dont loose them when you turn down

No pickup is going to change the way The circuit behaves

Works for me.

I have my neck pickup wired with the coils in parallel instead of in series. Added the PRS style treble bleed (just a cap) and didn't like it, tried a Kinman style cap and resistor and did like that. 50s style wiring apart from that.

Oh, and the resistor on the bridge pickup volume pot to make it react like a 250k (will replace the 500k with a proper 250k soon).

Worth experimenting, cheap to try out.
