Electro-Harmonix Q-Tron XO Envelope Follower

Small size, big funk tones. That’s what the DR. Q Nano envelope filter guitar effects pedal from Electro-Harmonix is all about. Its intuitive control layout is dead simple. A single knob controls the range while a Bass toggle lets you give your signal a quick low-end boost for some added oomph. The Dr. Q Nano is very responsive to your picking dynamics and guitar volume; giving you different and unique sounds depending on how hard you attack the strings.

Few envelope filter effects pedals can come close to the tone-shaping power and precision that the Riddle: Q-Balls For Guitar brings to the table. This envelope filter pedal from Electro-Harmonix lets you dial in some truly expressive and funky tones using adjustable Q, sweep range, and filter type. Plug in an expression pedal and you get even more control over the Q frequency’s sweeps. There’s also a dedicated Distortion effect that can dish out everything from a subtle bite to an all-out crush.
