The Crybaby 535Q is the Swiss Army knife of wah pedals. It provides control over the most important wah parameters, making it easy for you to create your ultimate wah tone. Its six-position Range Selector control allows you to choose from six different frequency ranges, each position based on the unique tonal characteristics of our most prized wah specimens. The Variable Q control allows you to take the 535Q's response from narrow and sharp to broad and subtle with the twist of a control. Once you've got your sound, make sure it gets heard with the switchable boost-adjustable up to 18dB that can create endless sustain on any note.
