What is the best route to adding a USB power source to a guitar amplifier? Answered
My girlfriend has a Fishman Loudbox Mini amp which has a 3.5mm auxiliary input on the back. She bought a cheapo bluetooth audio receiver that is powered by USB and outputs through its own 3.5mm jack. It works great but it takes up two wall outlets, and drastically reduces the distance it can be from the wall due to a short audio cable.
So I need an easier power source for the USB dongle. I had imagined a coupler that would sit between the amp and its power cable. I could frankenstein a USB-wall-outlet connector into this coupler to provide a USB power source close to the aux input. However it may be easier to find a 5V source inside the amp and just add a usb port. I'm not sure, which is why I'm creating this post.
