BF-10 Infinite sustain and extra definition. Our unique compressor pedal works like this: it calms down the loud notes that stick out and gives a kick in the butt to the humble ones. And there you have it - an evenly leveled playing that sounds natural. You can personalize your tone by adjusting the sustain, attack and tone parameters. Unique construction uses a voltage controlled amplifier manufactured by the legendary THAT Corporation which provides you with amazing dynamics and low noise. It features a true bypass mode and SCS compatibility.
