Spectrum Analyzer

The Spectrum Analyzer is a visual device which reads audio information and displays it in 7 frequency bands, from 63Hz to 16kHz, represented by classic LED Bar Graphs. It reads information from any source that can be plugged into it—a computer, a guitar, a synth, a cellphone—or it can read the sound around it through a built-in microphone. Like all Dr. Scientist pedals, the Spectrum Analyzer can be used with guitar, bass, synths, and many other instruments.

FAQ

What does this do exactly?

The Spectrum Analyzer is a purely visual device.  It displays the levels of the frequencies of your audio signal on the big bar graph LEDs, dynamically and in real time.  It doesn't affect your signal at all, it merely monitors your signal and displays the frequency info.
