Treble Bleed/Volume Pot Mod?

Re: Treble Bleed/Volume Pot Mod?

Let us know if you find values that work for the Duncan style (parallel) treble bleed. I tried one and noticed that it didn't taper wat so ever and gave up.
 
Re: Treble Bleed/Volume Pot Mod?

Did you give up on TB mod altogether or switch to Kinman?

I tried it through a few amp sims now and with high gain and compressed settings, I noticed very little if any tapering whatsoever. With more rock and crunch tones, its very clearly there and works great. Will have to wait for a few weeks to try it through my actual amp.

Yeah, Duncan style works the worst. Kinman works better, but simple works totally fine. Around 200pf cap for moderate brightness as you turn down and 3 - 400pf for hella brightness as you turn down.

Oh wow, really? I bought components to try it with a 1200 pF cap and 130 k resistor. That's what I found as a recommendation when I googled around.

Stewmac sells ready to use ones as well and include diagrams for most everything they sell. Never used it myself but figured I'd point it out. They also sell the individual components to do your own if you'd rather!

That's seems pretty pricey. There's a big electronics specialty shop hereabout, so I buy stuff for a few cents each.

Ok, so I just got done swapping the duncan mod for the Kinman, here are my stray observations so far (about three minutes of playing). Again, for future reference, here are the component values I used:

Duncan - 2.2 nF cap, 100k res
Kinman - 1.2 nF cap, 130k res

1: The issue with very little tapering taking place on with high gain tones remains, though it's less pronounced
2: There seems to be an overall brightness lingering in my tone, even when vol pot is fully open. Could possibly be because old and worn pot, though.

The idea to use the treble bleed to, as they say, "ride the volume pot" is probably not gonna happen. I wanted to try this because I have an OCD clone and heard it responds really well to adjusting the volume. Still gonna try it, ofc. That being said, I do like the mod despite what it does to my volume roll-off. IMO, the trade-off is worth it, esp considering how well it works one clean and crunchy tones.

Also, gotta pat myself on the back here - after first plugging the guitar back in, I noticed the bridge pup was kinda thin sounding and low in output. Correctly identified it as a cold solder joint and remedied it. Not bad for a soldering n00b, if I may say so myself :)

Nice job, soldering is fun.

I've noticed that too that it seems big value treble bleeds can pump extra highs through even with the volume on 10.

Just use a cap alone. Not too bright, doesn't screw with your taper. Start with 200pf range and adjust up or down if you need to.

Yeah, I'm thinking next step is getting some gator clips and trying things out one at a time. Heck, there is ample space in that control cavity. I could even to something like connect two longer cables to the pot lugs with metal loops at the end so I don't have to keep removing the pots whenever I want to access them.



I have a different approach to baking off volume & adding treble: spin-a-split.

A somewhat more drastic surgery, though [emoji6]

Not really. Just wire the existing tone control to be a 2nd volume pot for a HB, but just for one coil (the 'hot' wire would be the red & white wires on Duncans that are usually taped off together). Just a little basic soldering. I've done it to most of my neck HB's, so I can get a sharp high end, and a less fat tone. Sometimes neck HB's can sound pretty warm & thick.

Ah, thought you meant drilling for and installing a third pot
