Used Electro-Harmonix Qtron + Effect Pedal

Add funky, touch-sensitive filter sweeps to your rig with this used Electro-Harmonix Q-Tron+ envelope filter in good condition. Based on the classic Mu-Tron III vibe, it delivers auto-wah quack, vowel-like tones, and synthy squelch with selectable low-pass, band-pass, or high-pass modes. Dial in response with Drive, Q, and sweep controls, plus switchable Up/Down sweep. Works great for guitar or bass and runs on standard 9V DC power.
