The Dunlop Cry Baby 535Q Copper Limited Edition is an analogue wah pedal engineered to combine the classic Cry Baby sweep with expanded tonal shaping capabilities. Its enclosure features a distinct copper finish, and like other Cry Baby models it uses a rocker pedal design to control the wah filter in real time. The rugged chassis and expression-style foot control make it suitable for stage and studio use, providing a familiar tactile response for expressive playing.

Unlike a traditional fixed-voicing wah, the 535Q includes a set of adjustable parameters that let players tailor the pedal’s frequency response and character. Controls include Frequency, Q (resonance), and Wah Level knobs, which allow adjustment of the sweep range, the sharpness of the peak at the sweep’s centre, and the overall output level. This flexibility enables a broad palette of sounds — from vintage vocal wah tones to more pronounced, aggressive sweeps — without external controls or additional pedals.

Hardware features true bypass switching to preserve signal integrity when the effect is disengaged, along with a standard 1/4″ input and output and a DC power jack for external power supplies. The pedal accepts a 9-volt battery or an external adapter, making it adaptable to pedalboard setups. The combination of classic wah functionality and enhanced control options make the 535Q Copper Limited Edition a versatile choice for guitarists seeking both traditional and modern wah sounds.
