Tech 21's all-analog circuitry extracts straight, vintage tones from each Boost Series pedal with modern reliability. Designed and built from the ground up using the finest individually selected, hand-tuned discrete components, each unit delivers optimized performance with quiet studio operation. And we call them Boost pedals for a reason. In addition to a multitude of warm sounds, there's a powerful boost function that provides up to 21dB of incredible net boost, which can be used independently of the effect. It's a true post-boost, reinforcing the tone you've dialed in without smothering it in unwanted distortion.
