The Joyo JF-11 6 Band Equalizer pedal is a graphic EQ custom-tuned for guitar, though equally useful for bass and keys. Each band gives you +/-18dB boost and cut with smooth, musical curves that make tone shaping as easy as can be. Great on its own or as a tone-shaper for your favorite distortion pedal with a more limited tone control section, the Joyo 6 Band EQ has lighted sliders show your settings while you're on stage in a dark club, and true-bypass switching so your tone isn't altered in any way when the pedal is disengaged.
