NAMM '11 - QSC KLA Active Line Array System

Fat envelope and wah sounds are made even wilder with the help of an expansive octave effect that can be used in tandem or independently from the filter.

For those that haven’t delved too deeply into the subject or the sounds, envelope filters can seem a little loaded, stylistically speaking. Used well, they add bounce, joy, or even menace to a guitar or bass. Used wrong, they sound horribly corny. Used unconventionally, though, they can radically reshape guitar tones in surprising ways. Leveraging how they reshape tone with picking dynamics, for instance, is a great way to bust out of a box. They also pair well with distortion, fuzz, delays, modulation, and more (though if you aren’t willing to dig for gold in these combinations the results can confound at first).
