Hey, I've been playing my bass more lately (a dumpy Silvertone starter p-bass that's been tweaked extensively to get good action) and, as primarily a guitar player, I find the string spacing on a 4 string (mine is around .8 inches between strings) to be fairly uncomfortable and one day had the thought to squeeze a 5th string in, thereby solving two problems. The first problem being the string spacing, the second being my desire for extended range. Right now the overall string spacing is about 2.4 inches using barrel saddles on the bridge. I've researched adjustable bridges and there's a few that could pull off 5 strings at or near that width, namely Schaller and Hipshot. Right now I'm still gathering information to determine whether this bass is worth upgrading (I plan to completely overhaul it if I decide to convert) or whether I should just try to find a narrow 5 string that I like to buy instead. I have guitar building experience so the labor isn't really an issue, and I do have a preference towards upgrading philosophically, but if it means putting hours and hours of work into a disappointing final product I won't waste my time. So I guess my question is, has anyone heard of this being done and have any links to examples? It seems like it should work and from what I estimate the spacing for 5 strings should be just what I want on my neck. I'll have to find or file a nut and figure out how I should handle placing the 5th tuner, but otherwise it seems fairly simple. I'll likely be converting it to 5 string jazz pickups on the electronics side.
