So I just purchased a cheap $30 bass off of Craigslist. I'm a guitarist/mandolin player who wanted a bass to fiddle around with. And of course a couple of the tuner keys bust as I'm putting new strings on. I just spent $30 on the bass and $24 on the strings. Everywhere I look online for replacement tuner keys are around $24+. Is there a good site where I can purchase them at a cheaper price? Help me out!
