JOYO WAH-II Compact Wah/Volume Guitar Pedal with 6-Mode Sweep and Q Control

A wah pedal built for a single effect keeps things focused, the JOYO WAH-II adds active volume control in the same compact unit. Switch between Wah-Wah and Volume modes, then shape the wah response with six sweep ranges and an adjustable Q control. Its compact format is designed to take up less pedalboard space.

How it fits

Use the side switch to choose Wah-Wah or Volume mode, depending on what the part calls for. In wah mode, the Range knob selects among six frequency ranges, while the Q knob adjusts the character from sharper and more focused to broader and mellower. That gives players room to tailor the sweep for rhythmic accents, expressive passages or a more prominent lead sound.

In Volume mode, the active circuit is paired with a Minimum Volume knob. Set the heel-down level to suit the transition you need, from a quiet starting point for swells to a higher floor for moving between rhythm and lead parts. For a player choosing between a wah-focused setup and one pedal that also handles volume, the WAH-II brings both functions together without taking the space of a traditional full-size wah. The manufacturer also confirms bass compatibility, making it useful across guitar and bass rigs.

Why it’s worth it

The two functions serve different moments in a set: the wah sweep adds a moving tonal accent, while volume mode lets you shape level with the treadle. The six selectable ranges and adjustable Q make the wah sound more adaptable than a fixed sweep, and True Bypass preserves the signal path when the pedal is off in Wah-Wah mode. In Volume mode, its circuit remains active to maintain signal quality.

The compact red housing is suited to a crowded pedalboard, and the two green LED indicators help make the pedal visible on a dark stage. Buyers often highlight its compact footprint, tonal adjustability and ability to dial in different wah sounds. Opinions on the volume function are more mixed, so its key appeal is the combination of selectable wah character and active volume control in one pedal.
