I figured this belonged in Setup more than Strings. I often come across posts that say "my bass almost never goes out of tune," where the person seems to be stating it's the bass' construction that keeps the string in tune. Guitar strings seems to go out of tune quite often, so I've thought that lighter gauges tend to go out of tune more. The tuner I'd imagine would play a big role, but I imagine the player would have the most to do with it-I've had very cheap basses and very high-end ones, and I've pretty much had to retune them both over the same duration of time. Is it a combination of all these things? Is one factor more prominent than another?
