The BoostBot is an always-on, ultra-compact clean boost with dynamic, real-time level display meter. The boost circuit is a classic op amp design, a clean and loud amplifier that sounds great and provides 20dB of boost. Displaying the signal level is a classic 10 Segment Bar Graph LED. Like all Dr. Scientist pedals the BoostBot can be used with guitar, bass, synths, and many other instruments.
