Nice to have in your bag, just in case your battery goes dead. Also nice to be able to charge your iPad through the pedal via the 9V regulated supply.
Specially, the power supply completes a great total solution with the STOMP pedal. It’s the best Bluetooth page turning product out there. So far I use it exclusively for music.
This power supply looks very sturdy and built for a life of gigs in the bars and dives I play in.
Very impressed with the product (9 volt power supply with daisy chain). Delivery time was very fast. That's the way to do it!
