Straightforward, expressive and built to last, the Rocktron Classic Wah pairs dynamic foot-controlled wah action with adjustable rocker tension and rugged all-metal construction. Its broad 400Hz–2kHz frequency range sweeps from a warm, full-bodied response at the heel to a sharper, more pronounced upper-mid character at the toe, giving you intuitive control over everything from subtle tonal movement to dramatic filter sweeps. Adjustable rocker tension lets you tailor the pedal's feel for firmer, more precise control or smoother, more fluid movement, with an included Allen wrench making adjustments simple. A traditional toe-operated on/off switch and red status LED provide familiar operation, while standard input and output jacks, an easy-access battery compartment and support for 9V battery or DC adapter power make the Classic Wah a practical, dependable addition to virtually any pedalboard.
