Kinman Treble Bleed Mod for Humbuckers - What Values Are You Using?

[donalddemon]

I've read up on this mod and also have it installed in my '94 LP Studio. The original specs were for 250k pots and single coils, a 0.001uF cap in series with a 130k resistor. Applying this to humbuckers, most (including myself) have converted that to a .001uF cap with a 240k resistor with 500k pots for humbuckers. That makes sense since the resistor value for the single coils is roughly half of the pot value, so the same would go for 500k pots.

I've been reading that it's a good idea to tune the capacitor value to the capacitance of the guitar cable. In this mod circuit, what does changing the value of the capacitor actually do? I'm getting ready to install this in my other humbucker LP type guitars but I wanted to mess with the different values to see what works best but I don't really know what the different values will produce, electronically.

What values have you experimented with and settled on for this mod with humbuckers/500k pots?

The resistor changes the taper of the high frequencies. You could skip it if you like the taper of the pot or its already a audio pot with a good taper.

I thought the main purpose of the resistor was to retain some lows in the treble bleed circuit as you roll down?

Hey man, if you're unsure of what values to use, you can build an easy-mount connector for quick swapping components. I wrote a thread about it, you can check it out here.

Cool, that's a good idea. I was curious what values people ended up with for their humbuckers since I haven't seen much on that. I ended up going with a 0.001 cap and 270k resistor for my Edwards LP with 500k pots.

The so-called Kinman treble-bleed circuit is the best (the same can be said for Kinman pickups). Concerning humbuckers, overwound pickups, and 500k Volume pots - 240...270k resistor is ok, but I am using less cap's value too - 680...820pF. Values depend on the pickup's impedance, the Volume pot's value, the Tone pot's value, the Tone cap's value, the pickup shunting capacitance until the next input, and the next input's impedance - I mean the pickup's complex loading. However, optimizing this circuit is very subjective too.

if donalddemon is still around I bet he started making apotropaic gestures

I'm a cap-only enthusiast my self, seeing as I prefer a brighter tone for cleaner sounds and a darker distortion sound

I'm digging the info.

I'm firmly in the cap-only camp too. It's nearly 40 years since I got my first PRS with that type.
Rather than looking for an even character, I prefer things brightening a bit as I roll back.
