The CostaLab Booster Fat is a true classic — the very first pedal to spark the CostaLab journey, and still one of the most beloved by players who demand transparency, power, and tone integrity.

A boost pedal may seem simple, but in the hands of professionals, it becomes a secret weapon. Whether on stage or in the studio, it's the perfect tool to cut through the mix and be heard when it matters. The Booster Fat delivers up to +26 dB of clean boost, with a smooth and controlled top end that avoids harsh harmonics, even when pushing your amp hard. The low-end remains full and tight, giving depth and body to your sound.

At the heart of the circuit is a Class A buffer, always active, designed to preserve every nuance of your tone. It provides greater definition, dynamics, and harmonic richness — not just a signal boost, but a refined tone enhancer that benefits your entire signal chain.


Its versatility makes it a must-have on any pedalboard:

– Used at the beginning of your chain, it pushes overdrives and distortion pedals with clarity and strength.

– Placed at the end of the chain, it increases overall volume for powerful, cutting solos.

– In the amp’s effects loop, it works as a volume controller or attenuator for high-powered tube amps.

Despite its ultra-compact size (just 37×92×30 mm), the Booster Fat is built with premium components that ensure low-noise, high-performance operation, and it features true bypass, a Class A buffer, and an anti-pop filter for seamless switching and clean signal flow.

Power supply: 9V DC (center negative), standard 2.1 mm connector

Current draw: < 20 mA

Pro tip: For optimal performance, use a filtered and stabilized power supply like our GIOVE, or any equivalent-quality adapter. Low-quality adapters may introduce unwanted noise or damage the pedal.
