Key Features

CLASSIC ANALOG DISTORTION — FUZZ & DISTORTION HYBRID TONE: The SPLINTER delivers a thick, saturated distortion tone through an all-analog design, blending elements of fuzz and distortion for a uniquely aggressive voice. From tight, articulate crunch to raw, roaring fuzz, the pedal covers the full spectrum of gritty, grungy tones with a touch-sensitive dynamic response that reacts naturally to picking attack and guitar volume adjustments. Players describe the sound as having "a great edge of breakup sound" and appreciate its versatility across a wide range of playing styles.
FAT & MOSFET TOGGLE SWITCHES — TWO UNIQUE VOICINGS: Two independent toggle switches provide additional tonal flexibility. The FAT switch adds thick, powerful low frequencies, suitable for heavy riffs and filling out single-note solos with a fuller presence. The MOSFET switch engages germanium diode clipping for a softer, more vintage feel with smoother compression, ideal for classic rock, blues, and dynamic lead playing. When MOSFET is off, the pedal uses silicon diode clipping for a brighter, more aggressive modern edge. Note: the difference between MOSFET and Stock clipping is most noticeable at higher DISTORTION settings; at lower gain, the differences become more subtle.
3-KNOB CONTROL — DISTORTION, FILTER & VOLUME: Sculpt your signature distortion tone with three intuitive controls. DISTORTION sweeps from subtle, edge-of-breakup grit to full-on, saturated fuzz. Start around 9 o'clock for tight crunch, push past noon for aggressive metal, or max it out for raw, roaring fuzz. The FILTER knob is a powerful tone-shaping tool—turn it clockwise to roll off high frequencies for a darker, smoother voice, or counter-clockwise for a brighter, more cutting presence. VOLUME adjusts overall output from unity gain to a boost that can push your amp into natural overdrive.
SOCKETED OP-AMP CHIP FOR CUSTOMIZATION: Unlike most distortion pedals that lock into a fixed sound, the SPLINTER features a socketed OP07DP op-amp chip that can be easily swapped for other popular chips to fine-tune tone. Different op-amps produce slightly different gain structures, compression characteristics, and harmonic content. Players confirm the JOYO version is "more responsive to the OpAmp changes in a way that you can actually hear." Note: opening the pedal to swap chips will void the warranty. Please ensure you are satisfied with the stock sound before attempting any modifications.
JOYO QUALITY & AFTER-SALES CONFIDENCE: Backed by JOYO's decade-plus reputation for crafting innovative, budget-friendly gear that punches far above its weight. Encased in a rugged aluminum alloy. Dual power options: use a standard 9V 6F22 battery (not included) for grab-and-go portability, or a 9V DC adapter (center negative, not included) for consistent power. Rated current: just 20mA—exceptionally power-efficient for extended battery life. For the quietest performance—especially with high-gain analog distortion circuits—use a regulated, isolated 9V power supply and avoid daisy-chaining with other pedals. Should any issues arise, please contact us through your Amazon order page.
