The Electro-Harmonix Nano Q-Tron envelope filter effects pedal is a versatile effects modulator that’s suited to a wide range of genres and instruments. The Nano Q-Tron responds to the user’s playing style and dynamics, with the input signal’s volume controlling the cutoff or center frequency of a swept filter. The results are tone-altering effects ranging from subtle to dynamic, auto-wah to ultra-funky—all inspired by how you play and highly interactive.

• Drive control adjusts the filter sweep sensitivity and how the pedal responds to the user’s dynamics
• Q control sets the peak bandwidth, determining subtlety or dramatics of the effect
