Fulltone FB-3 Fat-Boost Overdrive Pedal (Clean Boost to Tweed Crunch).

Fulltone Fat-Boost FB-3 (FB-2 / FB-3) – Discrete Class-A Clean Boost / Overdrive Pedal

The Ultimate Transparent Post-Drive Clean Boost & Tone Enhancer—Discontinued & Highly Sought After.

Up for sale is a legend of transparent boost and tone shaping: the Fulltone Fat-Boost.

Known for building some of the most bulletproof, uncompromising stompboxes in guitar history, Michael Fuller designed the Fat-Boost to be an "always-on" secret weapon. Whether you need to slam the front end of your amp into natural compression, lift your solos above the mix without changing your core voicing, or add fatness, warmth, and touch sensitivity to your signal chain, this pedal delivers in spades.

Why the Fat-Boost is a Board Staple:

• True Class-A Discrete Circuitry: Built with high-end audio components that preserve the natural character of your guitar and pickups. It doesn't color your tone—it just makes your tone bigger, bolder, and more authoritative.
• Interactive Controls: Features dedicated Drive, Treble, Bass, and Volume controls. Unlike a one-knob clean boost, the onboard active EQ allows you to surgically tailor your low-end punch and top-end air, making it equally brilliant as a pristine clean boost or a gritty, touch-sensitive low-gain overdrive.
• Massive Output: Capable of pushing massive unity-gain boosts that can wake up any sleeping tube amplifier or drive downstream pedals into rich, musical saturation.

Versatility in the Chain:

• As a Front-End Enhancer: Place it early in the chain to add warmth and a three-dimensional feel to single coils or humbuckers.
• As a Post-Drive Master Boost: Placed at the end of your overdrive/fuzz section, it acts as a true volume multiplier—giving you a massive perceived lift for leads without altering the gain structure of the pedals coming before it.
• Pedalboard Built: Famous for Fulltone’s indestructible heavy-duty steel enclosures, true-bypass switching, and road-worthy reliability.

Condition & Details:

• Scarcity: With Fulltone having closed its doors, original units like these are increasingly hard to come by on the secondary market and continue to hold their value among tone purists.
• Cosmetic/Functional: Unboxed but full working condition.
