It's an amazing NOISE GATE. And a BOOST!

PYLON ATB Noise Gate seeks to not only drive back the hordes of buzz and hum, but also arms and reinforces your tonal attack, shutting down the noise and yet helping you enjoy your rig’s true potential.

This advanced, multi-functional and super-versatile pedal not only features an ultra-fast Gate with a smooth trigger, an integrated Boost section, an External Trigger Input for external bypass switching or Gate-triggering, a relay-based Channel Switcher for your amp but also sports a built-in Audio Transformer to help enhance and balance your rig. Hear and feel the quiet in the eye of the storm!
