The WD7 Weeping Demon is a versatile wah pedal by Ibanez with a broad array of controls, enabling its use in many playing styles and situations. It features spring and normal footboard action, an independent footswitch, auto-off delay, frequency range selector, frequency range fine tuning, level control, and adjustable Q and low-pass filter (called LO on the pedal). Both the pedal friction and spring tension are also adjustable.
The pedal is powered by one 9V battery or an optional AC adapter (sold separately). The WD7 also features an LED indicator that alerts you when the effect is on and serves as a battery check to inform you when to change the battery. The three "Tone-Lok" knobs can be pushed down to rest flush with the pedal's body, which will help maintain their settings and protect them during transportation. The circuitry is true bypass, so that when the effect is off your tone remains uncompromised.
The range fine tuning allows fine tuning within either the low or high range switch settings
