PRS Guitar Interface/DI These are preamps with balanced outputs, but the reason they are not simply a preamp is that the inputs are designed to match up better with the higher impedances you see out of magnetic and especially piezo pickups. It is for putting between a guitar and a mixer or interface to get a better impedance match. They can run on batteries(2x9volts) or a 12v adapter. I have one adapter. 40$ for a unit with ac/dc adapter 30$ for a unit without ac/dc adapter I know they called it an Interface, but it is not a usb thing. These are all analog. Cheers
