BOSS Over Drive OD-1 Boss Overdrive This is a guitar effector. It's a made-in-Japan model, which is rare these days, and is a so-called "silver screw" type, making it a valuable effector. It was passed down from my father's generation, and I also used it, but I no longer have the opportunity to use it, so I'm putting it up for sale. As you can see in the photos, there are some external damages, but it doesn't affect the performance or the internal components, and it produces the sound characteristic of a Boss overdrive. Operation confirmed. One of the knobs is missing, but it functions without any problems. It has been cleaned and disinfected, and stored in a dark place. I would be happy if someone would take this effector. Price proposals accepted. Price reduction requests accepted. Immediate purchase accepted.
