The Electro-Harmonix Doctor Q Nano Envelope Filter is a compact pedal that's not exactly small on the funk.

The envelope follower reacts dynamically to the volume of your picking, creating a wah-like tone that moves with how loud or soft you play individual notes or chords.

Actually can even sound cool with metal. I play exclusively through all tube amps with 8 string guitars loaded with …
