PRODUCT DESCRIPTION
- The Electro Harmonix Q-Tron is an envelope filter that responds dynamically to the volume your playing. Get ready for some funky wah-wah tunes! How does the Electro Harmonix Micro Q-Tron work? The Micro Q-Tron serves as an envelope filter for your signal. The Drive knob of the pedal controls the sensitivity of the effect. Turn it to its 12-o&apos
- clock position for normal operation, or turn it either left or right for some more dynamic results. The Q knob controls the peak bandwidth of the filter, and the Mode knob allows you to select the Low Pass, High Pass or Band Pass filter. Choose the Low Pass filter, for instance, to apply the effect to the lower frequencies. In practice The Q-Tron is a great way of finding out what a filter pedal can do. The concept resembles that of an auto-wah, but this Electro Harmonix pedal is capable of much more. Test it yourself to find out what is can do for your sound!
