Classic funk/rock envelope filter with a ton of quack, sweep, and character. This is the upgraded Q-Tron+ model with switchable effects loop and boost, giving you more control and flexibility than the standard version.

✅ Fully functional, sounds killer

✅ Great for funk, jam, and experimental tones

✅ Used but in good condition (normal wear)

✅ Comes with power supply (if you’re including one—delete if not)

Electro-Harmonix builds these like tanks, and the Q-Tron+ is a staple on pedalboards for everything from Jerry Garcia tones to filthy funk bass lines.
