SG electronics fun.

Well I wasn’t able to get to the bottom of whatever was happening with my attempt at 50s wiring, so I reverted back to modern and added a .001uf cap and 150k in parallel to form the treble bleed on each volume pot.

Eventually I may pull the PCB and fully rewire to 50s spec but at least initially the treble bleed gets me where I want to go so I’m going to live with it for a couple weeks and then evaluate.

Well, now I’ve done it.

I soldered the new caps from the middle lug of the volume pots to the left-most lug on the tone pot and now the pickups sound like the tone knobs are rolled all the way down and the tone knobs don’t do anything.

I assume you mean “leftmost” as if looking into the cavity. Just going by that assumption, it should be right most lug on tone pot. Then the middle gets grounded.

Seymour Duncan has the best diagrams imo:

The mistake is you still had the other rout live on the pcb.

Parrish treble bleed

Can you elaborate what exactly that circuit is?

It’s a capacitor with a resistor in parallel and a resistor in series. It takes away the extra crispiness of the lower volume settings and keeps the taper of the volume control much better than leaving one or the other resistors out. It’s the best of two versions rolled into one.

Thanks! Any decent values to start with for alround-ish noiseless pseudo-singlecoils and medium output humbuckers when using a 500k pot?

I always start with the original version and only change something if I don’t like it.

Dang, i really do have to build my decade boxes for this purpose. I’d have a definitive answer already.

I have an idea for this. Let me work on a few things.
