The Dunlop 535Q Cry Baby Multi-Wah is a versatile wah effects pedal for guitarists that allows for precise control over the wah effect. It features a Six-Position Range Selector to choose different frequency centers, a Variable Q Control to adjust the sharpness and width of the wah's frequency sweep, and a Switchable Boost Circuit that can add up to +18dB of volume for sustain. These controls work together to let players customize their wah tone, from narrow and sharp for funk to broad and subtle for rock and blues, making it a highly adaptable "Swiss Army knife" of wah pedals. 
 Key Features

• Six-Position Range Selector:This dial lets you select from six distinct frequency ranges, each based on the sonic characteristics of famous vintage wahs. 
• Variable Q Control:The "Q" refers to the quality factor, which determines the width of the wah's resonant peak. Adjusting this knob from a narrow Q creates a sharp, focused wah, while a broader Q produces a smoother, more subtle effect. 
• Adjustable Boost Circuit:A built-in boost provides up to +18dB of signal enhancement. This can be switched on or off and used to add sustain to notes or to make the wah sound louder. 
• Hardwired True-Bypass:The pedal uses true bypass, meaning the effect is completely disengaged from the signal when the wah is off.
