Circuit - PMT, Variable Treble Bleed
Precision Music Technologies V-Treb – Variable Treble Bleed Bypass Circuit. Made in USA.
The V-Treb Variable Treble Bleed Circuit attaches to the bottom of any volume pot and corrects the problem of high frequency losses at reduced volumes by allowing the player to control how bright or warm the tone will get as the volume control is reduced. Turning the trim pot clockwise increases the amount of treble bypass for a brighter sound at reduced volumes. Turning the trim pot counter clockwise reduces the amount of treble bypass for a warmer tone at reduced volumes. With the volume at 10, the V-Treb is removed from the circuit and does not affect the sound.

I installed the 500k CTS version on a dual humbucker guitar and I’m noticing that when the guitars volume is decreased the clarity is there as advertised but there is an additional bump in the mid range almost like I have a wah pedal on in the “toe” position. I’ve used/tried several other TB circuits and haven’t ever noticed a mid bump. Is there something in this item that might be causing that?

This is a passive circuit, and it may be that you need to adjust the internal trim pot to taste.
I did try lowering it all the way down to see if it eliminated the mid boost I was getting and it was a little better but not much.
Are you sure it is hooked up and adjusted correctly?

Is this the "Duncan" or the "Kinman" wiring?
Asked by Anonymous on October 13th, 2020.
Both the "Duncan" and the "Kinman" treble bleed circuits are simply a cap/resistor combination and can not be adjusted to taste like this unit.
The Kinman style is with the resistor in series. I believe this is a parallel cap/resistor combination.

I see this attaches to the Volume pot as an adjustable treble bleed. Does this mean I do NOT need a capacitor on my Tone pot? Thanks!
Asked by oregon4418 on July 13th, 2019.
That is not the case. This simply retains the high frequencies when rolling down the volume knob. If you want a funcioting tone knob, an additional potentiometer as well as a capacitor will need to be included in the circuit.
Product Reviews
My favorite treble bleed system. Once you adjust it the tone stays the same when you turn the volume down on the guitar. I hooked it up on two remote wires on my strat so I could adjust it while playing and got it just right then mounted it on the pot. Works great. This one is for my tele
Simple, elegant solution to treble bleed that's easy to install. Adjustable pot lets you adjust the amount of correction. Fixed the almost unusable volume knob on my Danelectro!
