Tech 21’s all-analog circuitry squeezes righteous, vintage tones out of every Boost Series pedal with modern dependability. Designed and built from the ground up utilizing the best individually-selected, hand-biased discreet components, each unit delivers optimized performance with studio-quiet operation. And we call them Boost pedals for a reason. Alongside a wealth of hot driven tones, there is a powerful boost function that delivers up to an incredible 21dB of clean boost, which can be used independently from the effect. It is a true post-boost, punching up the tone you dialed in, not smothering it in unwanted distortion. From the high-impedance input to the sweepable low-pass filter in the tone control, your tone will be open and controllable in every setting.
