Does anyone have any info regarding tuners for an older Ibanez Musician Bass. The gears on my 'G' string tuner have stripped and will no longer come up to pitch. Most of the after market tuners I have found require a 9/16" hole for the machine head, however my older 'Musician' has an approx. 11/16" (.662") hole in the headstock. Ibanez is of little help. I've only been able to reference replacement parts back to a 2000 vintage (my musician is a 1979 vintage) and Ibanez does not reference size specifications for the tuners that they do offer. Am I really going to have to trash my vintage instrument over this small problem? Any help from anyone with a similar experience, or other technical knowledge/advice is greatly appreciated.
