Treble Bleed; Variants and personal experiences?

[Tretgeraet]

Hallo Leute,
I just finished my telly build and in the wiring kit I bought from Rockinger, they included a treble bleed, in this example a 150k resistor and a 1nF capacitor in parallel, wired between the hot and middle lug of the volume pot.

I really like the effect and decided that my 7/8 S-Style, having only one humbucker and one volume pot, needs something like this, too.

But Rockinger shys away from giving recommendations, stating that the right recipe is depended on personal taste and which pickups and wiring is used and also what else is in the signal chain, like fuzzes, treble boosters, etc.

So, I'm going to have to experiment, but also, I'm asking you if anyone of you has personal experiences and/or preferences regarding treble bleed.

The guitar in question has a Seymour Duncan '78 model (low to medium output AlNiCo 2 humbucker) and a 500k volume pot. I use it mainly to play Metal, but I also play a huge variety of styles and strive for maximum versatility, as Aaron would call it. I hope everyone here knows what that means.

Any experiences? Any recommendations?

You can see the values I use in the diagram in the below post. Basically the same.

Without further ado... an update with the treble bleed shown and a couple of minor tweaks.

If a treble bleed works, then that is about the only thing it is going to do. Don't overthink it.

You, sir, are a man of intelligence and taste.

I really like treble bleeds. I've tried some that are fantastic, and some that were really awful. My two favorites are:

The one that comes on PRS pots found here, which are also my favorite pots in the whole world. They are stupidly expensive, and I know people claim they are just rebranded Bournes with a massive pricetag, but I've never found any other pots with such a perfect sweep, and the treble bleed is likewise perfect.

The other one I like is the mojotone one here.

Ok, now we have all 3 treble bleed variants I already heard of before:

1nF parallel with 150k (Rockinger / Stratamania)

470pF parallel with 220k (Mojotone)

180pF without parallel resistor (PRS)

I understand the basic principal of the capacitor being a frequency dependent resistor and I think I understand the parallel resistor is meant to counteract the sound getting too shrill at low volumes.

What I don't understand is, why the capacitor values are so much higher, when there's a parallel resistor.

And yes, this might be overthinking it, but it's also fun. I like to understand things.

I use 150K and 1,000pf (1 nf) in my builds.

I've been using variable/adjustable treble bleed circuits in my builds like this one on Reverb

Basically it's got a little trim pot so you can adjust how much treble bleed you're getting

Don't make me regret what I said before.

Thank you, that's an awesome build (or wuilt?) you did there btw!!!

1nF is a large value in the context of treble bleeds, which tends to be used for Telecasters. You could keep a similar circuit and swap it for 680pF, which makes it closer to what Suhr put in their guitars.

Ibanez sometimes use 330pF, but with no parrallel resistor and that is a very noticeable effect IMO.

I always use the MojoTone (220K resistor in parallel with a 471pf cap) since I already order all my pots from them (modified CTS). Have always been very happy with them.

Volume Mod for Guitars

Keep more of your tone! This is a 220K resistor in parallel with a 471pf capacitor. The capacitor acts as a treble bleed to preserve high end frequencies, while the resistor improves the taper when rolling back your volume potentiometer.We use these in many of our pre-wired guitar...

I like the Kinman treble bleed myself, but there are many others to consider...

I found that a little hard to read, but... isn't that for tone pots?

I explained some of this in an earlier post, there are also some links in that post should you wish to dig deeper.

A few things to answer here so I have unpacked it to separate things out.

Are those active pickups?

No they are passive. the pickup types are mentioned above each pickup - remember it is a diagram and each symbol is not meant to be totally exact like a photo.

(I have active pickups in other guitars by the way)

Is that the little black boxes with red wire going to the pickups?

The red and white wires are going to a black rectangle - it represents that the series link wires of each humbucker are joined together and the black symbol you could think of as the join with...

For humnbuckers i do what prs does. For strat i use dimarzio s method. I can't remember the values but it works. Teles i do without.
