Electro-Harmonix Q-Tron Plus Envelope Filter with Effects Loop

Description

The Electro-Harmonix Q-Tron Plus Envelope Filter with Effects Loop is a Q-Tron enhanced envelope controlled filter and is a powerful tool for musical expression. Envelope controlled filters are unique sound modifiers, and the intensity of the effect is controlled by the user's player dynamics. The volume (also known as the envelope) of the musician's notes is used to control a swept filter. As the volume of your notes changes, so does the peak frequency of the filter.

The effects loop gives you the ability to place an additional effect, or chain of effects between the Q-Tron Plus's preamp and filter section without changing the envelope drive. This is particularly important with most distortion devices. The FX loop will also fire up your creative juices to try all sorts of combinations in the effects loop. The added Response Switch selects between a slow, smooth, vowel-like attack and the fast, snaked response of the original Q-Tron. The Q-Tron can be used with a wide variety of electronic instruments.
