I have a source for sets of ebony tuner buttons for any Larrivee guitars.  For 20 bucks, makes a very nice little upgrade - I really like the look it gives, and they just 'feel' better, in my opinion.  This is the best price I've found for them anywhere.
They are two different sizes.  The normal type, and a smaller type for use on the mini-Ping tuners on the Parlor guitars.
Email me privately & I will give you the sellers email address.
