Key Features
- BASS PREAMP & DI WITH 6-BAND GRAPHIC EQ: The MONOMYTH delivers studio-grade tone shaping with a dedicated 6-band graphic EQ—giving you surgical control over your bass tone. From tight, punchy slap to warm, round fingerstyle, the EQ sculpts your sound with precision. The balanced XLR DI output with Ground Lift lets you connect directly to PA systems, audio interfaces, or front-of-house mixers—no amp required. Players describe the tone as spanning from jazz to doom metal.
- BLEND, VOICE, LEVEL & DRIVE — TOTAL TONAL FLEXIBILITY: Four dedicated controls give you complete command over your overdriven tone. BLEND mixes your clean and distorted signals—crank it for full-on saturation, or dial it back to retain clear low-end punch while adding grit on top. VOICE adjusts the character of the distortion—from tight, focused attack to open, fuzzy saturation. LEVEL sets the overall output of the drive channel, and DRIVE controls the amount of gain and breakup. Players describe the blend control as the key to retaining clarity while adding distortion.
- INDEPENDENT OVERDRIVE CHANNEL WITH TREBLE & GAIN BOOST: The dedicated Overdrive channel features its own footswitch for instant activation. Two independent Boost switches shape your driven tone: TREBLE BOOST adds high-frequency presence and definition—perfect for cutting through dense mixes. GAIN BOOST provides a low-end saturation boost—similar to a "Growl" control—for a fatter, more aggressive tone. Combine both switches with the Blend knob to dial in everything from subtle, edge-of-breakup warmth to full-on, roaring bass distortion with massive low-end weight.
- BUILT-IN CAB SIM & PROFESSIONAL CONNECTIVITY: The integrated cabinet simulation recreates the authentic response of a bass speaker cabinet, adding realistic low-end fullness and reducing high-frequency fizz. Note: Cab Sim is active on the XLR DI output only—the 6.35mm output and headphone jack pass your signal without cabinet simulation. Additional professional features include a 3.5mm headphone output for silent practice and a Ground Lift switch to eliminate ground loop hum in live settings.
- JOYO QUALITY & AFTER-SALES CONFIDENCE: Backed by JOYO's decade-plus reputation for crafting innovative, budget-friendly gear. The MONOMYTH is part of the R Series, built with upgraded precision components. Important: Powered by 9V DC adapter only (center negative, not included). Rated current: >200mA. Battery operation is not supported. For the quietest performance—especially with high-gain overdrive 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.
