Guitar pedalboard

Hard shell pedalboard-cases have foam padding, reinforced corners, and locking latches.

[1] Most effects pedals are powered by varying levels of DC voltage, depending on the manufacturer.

Switched-mode power supply noise can be reduced with low-pass filtering and a regulator, and by ensuring the switching frequency is significantly higher than the ~20 kHz upper limit of human hearing.

There are batteries on the market that can power over 20 effects pedals for eight hours on a single charge.

Using a rechargeable effects pedal battery or AC/DC power supply in conjunction with a “pedalboard suitcase” reduces setup time prior to a show.
