thanks! i'll look into that link...
yeah, the "D" tuner broke, the black plastic part, of course. funny thing: i played a 15 minute set at a jam, put the bass in the gig bag in a corner, three hours later i get the bass out to close the night and the D string had lost all tension, and the tuner was just hanging on like a loose tooth. i bent it back a bit and it fell off in my hand. i know nobody touched it the whole night, i guess it was just time for it to go...
the only other time i've had a broken tuner, also a "D" string tuner, was when i was one or 2 weeks into playing bass, tuned the string way too tight, "snap!", the thing couldn't take it, some generic bass and pre-internet so i couldn't find a replacement part, i just tuned the "G" string down to "D" and played a 3 string bass for a year and a half!
EDIT: i checked that link, they were out of stock on the chrome tuners. did some googling, found what i was looking for (and lots of parts to look at) at
www.darrenriley.com for 5$ cheaper than the other place.
