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.
These merchants probably sell this module. Huh?
