Assuming it is a 34" scale four-string, you're probably going to have to grab a five-string set and use the heaviest four. Since that will bump your "E" string up to .135" you may have to have the slots in your string nut enlarged. I'm sure there are people who tune down with a .110" "E" string, but on a 34" scale bass, that is asking a lot.
