The BB Preamp offers a wide variety of tones. Its pre-gain stage allows this preamp effect pedal to deliver from clear and transparent sounds with no distortion to overdriven and compressed tones. We’ve built it in a red enclosure with silver knobs. Get it now at a very special price for a limited time! As all of our effect pedals, it’s True Bypass and runs on either a standard 9V DC Adapter or a battery.
