The Electro-Harmonix Micro Q-Tron is a compact envelope filter pedal offering a dynamic, player-controlled wah-wah effect. This pedal is ideal for adding a funky element to your sound, featuring adjustable drive and Q controls to shape the filter's sweep, along with low-pass, band-pass, and high-pass modes. Inspired by the classic Mini Q-Tron, it responds to your playing dynamics, with a stronger attack yielding a more dramatic effect. Its small die-cast case makes it pedalboard friendly, and is well-regarded for its ease of use and build quality.
