Boffin FX Push-Push Onboard Clean Boost Preamp 20dB 500K r Humbuckers, Super Strats & LPs

The Ultimate "Hands-Free" Solo Boost.

Stop searching for your boost pedal in the dark. The Boffin FX 20dB Onboard Push-Push Booster (2025 Edition) puts a studio-grade preamp directly inside your guitar.

The Push-Push mechanism is the gold standard for gigging guitarists. There’s no need to grip and pull—just a quick tap of the knob sends your humbuckers into high-output heaven. It’s the fastest, most ergonomic way to jump from a clean rhythm to a searing +20dB lead tone without ever looking down at your feet.

Why the Boffin FX 500K Push-Push?

• Engineered for Humbuckers: The 500K resistance ensures your humbuckers maintain their full harmonic range and top-end "bite," preventing the muddiness often found with lower-value pots.
• Instant-Engage Performance: Tap to boost, tap to bypass. It’s the fastest switching available, perfect for mid-song transitions and dramatic solo entries.
• Transparent MOSFET Circuit: Provides up to 20dB of clean, transparent gain. It pushes your tube amp into natural saturation while preserving your guitar’s core DNA.
• Onboard Trimpot Tuning: Calibrate your boost level inside the cavity. Whether you want a subtle +3dB volume lift or a full-throttle +20dB blast, you’re in total control.
• Treble Bleed Ready: Our 2025 redesign includes dedicated soldering pads, making it a breeze to add a treble bleed circuit and keep your highs crystal clear at any volume level.

Simple DIY "Drop-In" Installation

Designed for the modern player who wants professional results without the shop fees. Our minimal-solder architecture and pre-wired harness make the upgrade straightforward.

• Smart Power Switching: The included TRS (Stereo) Jack automatically turns the 9V battery off when you unplug your cable, ensuring your battery lasts for months of playing.
• Compact & Universal: Built to fit most standard electric guitar cavities (Les Paul, SG, PRS, etc.) as a direct volume pot replacement.
