Electro-Harmonix Micro Q-Tron

Electro-Harmonix · pedal

The Electro-Harmonix Micro Q-Tron is a compact analog envelope filter, condensing EHX's classic Q-Tron auto-wah circuit into a smaller pedalboard-friendly enclosure. It tracks playing dynamics to automatically sweep a resonant filter, producing funky, vocal-like auto-wah textures without needing an expression pedal, driven purely by how hard the player picks.
