Name of Product: BOSS DI-1 Direct Box
Serial Number: BB 70998
Production Date: August 1990
(Production date sourced from Boss Serial Number Decoder)
Have used this sturdy and dependable direct box since the late '90s as a direct interface between my bass and the mixing board for both recording and live performance. It runs on either a 9V battery or 24-48V phantom power from the board. I usually use an Energizer 9V alkaline battery as most of the boards I've worked with have not been that reliable. The only niggle concerning my DI-1 is when it is in Auto Power On/Off mode. In this mode, if I don't play for around 5 minutes, the DI-1 automatically turns itself off. My battery loves this thoughtful feature. However, when I come back after a break, the first note I play turns the DI-1 back on automatically; along with an annoying audible thump through my bass amp as well as the PA system (if I forget to turn off my channel on the board). It's a hassle, no doubt; but the tonal clarity and otherwise noise-free operation of the DI-1 make it a winner in my book. Enjoy the pics. Please note that any fur seen is from one of my cats or kittens, not me :).
