A Guitar And Gear Support Forum

this guy has one listed on local market for $2500... a 2017/2018 per him but...
what is that?
i asked him what it was and he said he didn't know which i find very fishy. it looks to me like the little button you put to cover a bridge doctor screw, but why in the world would you have a bridge doctor in a 2018 martin?

All I can say is that my 1980's D-28 does not have that screw, nor has any other D-28 I've ever met.
Smells fishy to me.

Special order from Ali Express?
