You may have noticed that when you turn down the volume control on some guitars (all vintage guitars), the tone changes too. The treble frequencies are attenuated, and the tone becomes somewhat dull. This is something that many people have never noticed - while it drives other people crazy - but if you check it out then you'll find that the tonal change really is there, even though you may never have noticed. And like many things, once you hear it, it's hard to un-hear it.

The treble-bleed is a resistor/capacitor (RC) network that can be used to address this problem. These things are used in many modern guitars, so if your guitar doesn't seem to sound any different at lower volumes than at higher volumes, then it's likely your guitar has one of these in it. It's easy to see, it's connected across two of the volume pot's three solder lugs.

There are different ways to use these. Some people use just a capacitor, while others use a resistor and capacitor wired in series. But the way that most of the larger players do it (Fender, for instance), is to use a resistor and capacitor in parallel, as shown in the image above. Of course, there are different values that can be used, and there is much debate on forum sites about what's wrong and what's right. And there are people who state that these things "kill your tone", etc. But that's not our experience, and we've put them under the microscope. In electronics, nothing is free. If you get a little over here, you give a little over there, there are no inconsequential actions. But our experience is that these treble bleed circuits pretty handily address the treble roll off. You can give one a try and see what you think.

Works great

Retains the highs while rolling off volume, just like it's supposed to do. Easy way to make your humbucker usable at any volume.

ToneShaper Treble Bleed Network

My first time using this treble bleed network, previously I'd just used a cap. So far so good!

John Smith
Works Great

Great time saver, good quality, works great, and reasonably priced. Component values are maximized for use with humbuckers - doesn't get any better!

Fat leads

These are nicely made, but the twisted leads result in a thickness that takes up a lot of space in a pot lug eyelet. They will not even come close to sharing the space with my pickup and cap leads. I'll have to use some thin jumpers to connect these. I think the resistor can be bridged across the cap leads and not twist around the full length; that could reduce thickness. Or maybe I'm the only one that has a problem with this...

Works as advertised. Quality is good.

Works great. I added some heat shrink to the feet as it can get busy around that hot lug.
