1303 Boost
The Supro 1303 Boost is a true tone connoisseur's secret weapon. This J-FET-powered pedal is the perfect companion for driving your tube amp into glorious, harmonic overdrive. What sets it apart is its uncanny ability to boost your signal with surgical precision, without sacrificing the inherent character of your guitar. The Supro Boost's simple yet versatile controls allow you to fine-tune your sound. The single Volume knob lets you dial in the perfect amount of gain, from a subtle push to a thunderous swell. But the real magic lies in the oversized toggle switch, which offers three distinct voicings: Bright, Flat, and Dark. The Bright mode engages a 3dB/octave high-pass filter, tightening up those humbuckers and adding sparkling top-end clarity. The Dark mode, on the other hand, introduces a 3dB/octave low-pass filter, fattening up single-coils and warming up your tone. The Flat setting keeps things perfectly linear, allowing you to sculpt your sound without compromising your guitar's natural voice. But the Supro Boost goes even further, offering a TRS expression pedal input that transforms it into a high-fidelity active volume pedal. This feature lets you seamlessly control the maximum and minimum levels, opening up a world of dynamic, hands-on performance possibilities. Handcrafted in the USA with premium components, the Supro 1303 Boost is a true workhorse, built to withstand the rigors of the stage. If you're seeking a transparent, responsive boost that will elevate your tone to new heights, this is the pedal you've been searching for.
