Electro Harmonix Micro Q-Tron Hüllkurvenfilter Gitarren-Effektpedal

I've used Electro Harmonix Ever since. Introducing the Micro Q-Tron pedal from Electro Harmonix. The Micro Q-Tron is a smooth envelope filter with a funky wah-wah tone. A stronger attack or louder note will produce a wider frequency sweep while softer playing produces more subtle effects.
