Fulltone WahFull
The WahFull is a pedal offered by the Fulltone brand.
Designed to be used as a fixed wah, it offers a volume control, 3 modes (Wacked, Jimi and Shaft), a microphone compensation (to be able to play on humbuckers), a JFET input and a buffered output. These buffers completely isolate the circuit from external influences and are only active when the pedal is engaged, which gives it a much wider effect, allows it to be used with more types of power supply, and makes it work with any type of high-gain or clean amp. It transforms a Fender into a Vox and gives infinite sustain with little or no distortion.
