In some embodiments, in response to attaching an instrument pedal to the pedalboard apparatus (e.g., via the pins and pin connector and via the magnetic regions), the pedalboard apparatus can indicate the status of the instrument pedal using one or more light emitting diodes (LEDs). For example, an LED indicator can provide an indication as to whether an instrument pedal has been activated or is in bypass by emitting a particular color light (e.g., a green light for an active state and a red light for a bypass state). In another example, an LED indicator can provide the rate of tap tempo (e.g. by causing an LED to blink at a particular rate or blink to a particular rhythm). In yet another example, an LED indicator can provide an indication as to whether an instrument pedal has been successfully connected to the pedalboard apparatus. In a more particular example, using an internal sensing circuit in the pedalboard apparatus, the LED can indicate (e.g., by blinking at short intervals) if an instrument pedal that is connected to the pedalboard apparatus is not functioning properly (e.g., where a replacement instrument pedal is needed to obtain the desired effect, where an instrument pedal is to be re-inserted into the pedalboard apparatus, etc.).
