I have a Collings MT2 and the inner D string tuner button just spins when I try and tune it up to pitch. This started when I was changing strings this evening. I am not certain if these are glued on to the gear post or not but I can not get the inner D string to tune. There are no screws on the top of the button to tighten.
Do I need a replacement set of tuners to fix this problem?
Any help would be greatly appreciated.
PS. I am the 2nd owner of this wonderful mandolin and I do not think the warranty is transferable. You think Collings would replace?
