Joyo R-12 10 band is a 10-band equalizer for electric guitar and electric bass that gives you more control over the sound of your instrument. 10-band covers the frequencies you need from 31.25 Hz to 16 KHz. 10-band also has a volume control so it can be used as a boost pedal.
Around the 10th To make band EQ more visible on the pedalboard, Joyo has equipped the pedal with LED lights on the bottom and top of the pedal housing. The light can be controlled via a switch on the back of the pedal, where there are 2 different lighting modes to choose from, as well as turn off when you need to save battery.
