I recently had an issue with mine and had to take it off my board. I temporarily put my Boss SD-1 overdrive in its place, but it is not the same at all, and I was really missing the LPB-1.I got one of these in a milk crate of stuff I bought 6 or 7 years ago.
I didn't even know what it was.
It went on my small board and never left.
I just fixed the LPB-1 a couple of days ago, and now all is right with the world again.
