Electro-Harmonix Q-Tron XO Envelope Follower

We don’t know who pissed Randy off, but his revenge is pretty darn sweet. The Randy’s Revenge effects pedal from Fairfield Circuitry is a tonally rich, all-analog ring modulator with that patented Fairfield edge. This pedal takes the whole ring modulation concept—multiplying the guitar signal with a sine wave or another simple waveform—by using not one but two simple waveforms in the mix, in this case, a sine wave and a square wave. This gives you a very wide range of highly musical tremolo and vibe effects.

The original EMMA DiscumBOBulator was arguably the world’s best auto-wah, making appearances at the feet of Ida Funkhouser, Richard Fortus, Warren Haynes, and Pino Palladino. When building the revamped version, Emma Electronic has improved the filter-triggering, extended the dynamic range, tripled the headroom signal, and added a 10dB independent boost. The DiscumBOBulator v2 features an extensive range of vintage auto-wah tones and new filter sweeps. It also boasts precise tracking, both on chords and single notes, and a wide frequency spectrum, making it perfect for virtually any instrument.
