I just bought a used Roscoe bass from GC (haven't joined the club yet, sorry!), and after putting some fresh strings on it (Dunlop Super Brights 40-100), I noticed that if I dug in a little too hard, I got some buzz on the open strings. I'm pretty sure the action on it is fine; I can drop the saddles flat on the bridge, add a little bit of radius for the middle strings, and the fretted notes up and down the neck basically play fine. The D and A are a little buzzy but mostly okay, but the E and G are both pretty bad. I can get rid of most of it by jacking up the saddles, but that makes the action harder to play on (not hard, but I'm used to playing my fretless, which has its strings just grazing the fingerboard). I'm wondering if I should just raise the action and deal with it, put on some heavier strings (not my preferred choice due to some minor arthritis in one of my fretting fingers), or just replace the nut. If I have to replace it, do you think there's any chance I can get the GC techs to do it as part of the purchase? The tech even mentioned that the nut was a little low, so maybe he will fix it as part of the sale (one can hope).
