Ultimate Tone Control for Any Guitar Setup
Elevate your guitar’s sound with the Boffin FX Hybrid Adjustable Treble Bleed Circuit—a revolutionary design that combines the best of parallel and series treble bleed circuitry. Say goodbye to muddy, dark tones when you roll off your volume knob. This innovative circuit ensures your high frequencies stay crisp, clear, and vibrant, no matter where your volume pot is set.
Whether you’re rocking vintage single-coils, modern humbuckers, or a complex custom configuration, this treble bleed adapts effortlessly to preserve your instrument’s natural brilliance.
Tuned for Sweetness: Low-Output & Neck Pickups
Electric guitars thrive on crisp high tones, but when you back off the volume, those highs are the first things to vanish. For bass-heavy neck pickups or warm, vintage-voiced coils, standard treble bleeds can feel abrupt or overly bright.
This Green Version (1,061 Hz) is specifically voiced to solve that problem:
-
Built for Neck Positions: Prevents naturally warm neck pickups from turning dull or muddy at lower volumes.
-
Perfect for Low-Output Pickups: Meticulously tuned to retain the airy, dynamic top-end of low-output single-coils and vintage humbuckers.
-
Peel-and-Stick Mounting: Features a clean adhesive backing on the bottom of the board for a seamless, rattle-free installation inside your control cavity.
-
Simple 2-Wire Install: Simply solder your hookup wires directly to the clearly labeled Input and Output pads on the circuit board.

Treble Bleed Frequently Asked Questions
Why does my guitar tone get muddy when I turn down the volume?
Passive guitar circuits act as a low-pass filter. As you roll off the volume, the resistance increases, causing high frequencies to bleed to ground. Our circuits counteract this by providing an alternative path for those high frequencies.
Which circuit type should I choose for my pickups?
For vintage-output single coils, the Standard (Parallel) is ideal. If you use high-output humbuckers or desire a very consistent tone throughout the entire volume sweep, the Kinman (Series) is generally preferred. The Hybrid allows for fine-tuning the balance between these behaviors.
Can I install this if I am not an experienced technician?
Our circuits are designed for straightforward integration. If you are comfortable with basic soldering, you can easily install these directly onto your existing volume potentiometer lugs.
Does this work with my onboard Boffin FX Booster?
Yes. In fact, many players integrate our treble bleed circuits alongside our onboard MOSFET boosters to create a fully optimized signal chain that maintains both gain and tonal clarity at any volume level.
