Generally speaking, the mechanisms described herein relate to a pedalboard apparatus that handles audio signals and musical instrument digital interface (MIDI) command signals from a musical instrument and from instrument pedals, while also providing variable voltages to each instrument pedal. The pedalboard apparatus can include multiple pedal attachment regions, where each pedal attachment region is configured to receive an instrument pedal such that, upon connection, the instrument pedal communicates with the pedalboard apparatus without requiring instrument cables (e.g., quarter-inch cables) between each instrument pedal and an amplifier and without requiring a separate power supply for each instrument pedal.

Note that the pedalboard apparatus is capable of operating in stereo, dual mono, mono input and stereo output, or any other suitable combination thereof.

It should be noted that an instrument pedal that is configured to connect with the pedalboard apparatus can receive an audio signal, such as an audio signal from a musical instrument, an audio signal from another instrument pedal, and/or an audio signal from a computing device, and can modify and/or manipulate the audio signal based on the configured effect associated with the instrument pedal. Examples of configured effects in an instrument pedal for a guitar can include a boost pedal, an overdrive pedal, a distortion pedal, a fuzz pedal, an Octavia pedal, a reverb pedal, an analog delay pedal, a digital delay pedal, a tremolo pedal, a chorus pedal, a flanger pedal, a univibe pedal, a phase shifter pedal, a compressor pedal, a volume pedal, a wah-wah pedal, etc.
