I was going through some old gear I had stashed away and found a pair of these power supplies. I was going to put them in use with some pedals, but wanted to make sure that 9.6v wasn't going to be a problem. I assume Boss made these for their pedals, so it should be ok.

Nevermind, I googled it. I was fairly sure it wasn't a problem, given variable tolerances and such, but was just checking.
