I love D'addario and DR 45-105 strings for bass. Those are my two favorite brands that I've used. Stay away from Ernie Ball strings. I used to break bass strings constantly when I used them, they lost their tone and sounded dead after only a couple hours, and they would rust up, and collect dust, sweat and anything that comes in to contact with them and get all grimy real easily. Since switching to D'addario and DR strings I never break strings, and I usually only change them after about 2 months of steady gigging and regular practicing. I've also heard from quite a few other bassists that GHS bass boomers are great, I didn't like GHS boomers for guitar so I always steered clear of them, but in the last couple months at least 3 or 4 bassists from other bands' I've played shows with have told me they like them.
Oh and also, the shop I bought my Rickenbacker from, when they set it up for me, they put a set of
THESE Smith strings on there for me and I really like the way they feel and sound so far, although I haven't had the bass long enough to speak about how long they keep their tone or how well they hold up after lots of shows and practice. But my initial feeling towards them is that they feel easier on my fingers than any other roundwound bass strings that I've played.
This bass is looking real nice by the way dude! Great job!
