The AceTone Mojo Work King (MWK-01) is a versatile overdrive pedal from the French boutique manufacturer AceTone Electronics (ATE). It was designed to bridge the gap between a transparent boost and rich distortion, with a primary focus on uncompressed, open dynamics. In plain terms, it aims to push an amp or add grit without squashing the natural feel of your playing, sitting alongside other designs covered on the Overdrive Pedals page.1
What it does
The Mojo Work King covers ground between a clean boost and a fuller distortion, which places it in the same broad territory as designs compared in Boss SD-1 vs Ibanez TS9 Tube Screamer, though AceTone's stated emphasis is on keeping dynamics uncompressed and open rather than compressing the signal hard.1
Its main hidden feature is an internal Voice switch. According to the maker, "An internal \"Voice\" switch allows users to toggle between a tight, focused drive and a looser character with enhanced" bass response. That gives the pedal two personalities: one suited to tighter, more defined rhythm tones, the other with more low-end bloom for a looser, more open feel.1
The pedal is handmade and uses premium components to ensure low-noise operation, per the maker's product information.1
The Voice switch is internal, so changing characters means taking the pedal off the board and opening it up, not turning a top-panel knob.
Power
The Mojo Work King runs on 9V DC, center negative, and draws 10 mA, a light load that fits easily on a standard pedalboard power supply.1
