I've got a relatively cheap-o- EUB. U know the type....... But all that's irrelevant really, it's got tuners like on a bass guitar- single ones-not joined by a brass plate or anything. Called Tyrolean????!!!?!???? I don't know really??? BUT I've been playing elec bass since I was 11y.o.(44 now) & the EUB for 5 yrs. Gigging with it evry week for the last 4 1/2 yrs. all without a problem with the bass. I have done some minor upgrades to it.:- a new bridge, replaced the cheapo preamp in it w/ a Fishman Platinum+pro, & it sounds darn good. Back to the tuner.......... The LOW E string tuner has stopped working! It turns but does not move the peg(or where the string is wound around) therefore I'm unable to tune it! It's STILL playable- just the E string is now an Eb string Can anyone give me a hint in how to remedy this problem. I DO have a set of replacement tuners, that LOOK like they'd fit, BUT I've never done thgis type of thing before & don't wanna go blindly in!!! Replacing pick ups, new pots, jack plugs.......-i.e. soldering is cool w/ me, bu that's about the extent of my bass specific handy work-other than a decent set up & fret levelling.... None of this matters for THIS particular problem tho.??????? Any help would be greatly appreciated! Thanks, Rod.
