A lot of snake oil indeed concerning pins.

However, Backwoodsman mentions adding mass to the bridge. There can be occasions when this helps. I have a guitar (Backwoodsman has heard me play it coincidentally) made by a local luthier that has a small light bridge made of lacewood to match the back and sides.

I had an annoying buzz which tightening the machine heads, dressing the zero fret, graphite in the nut channels etc just didn't cure. Last week I bought some brass pins as a bit of a last resort. I don't pretend to be an expert on guitars as such but my PhD in mechanical vibration does help the old thought process at times.

I seemed to be correct. The buzz on the top two strings has disappeared and recording a tune before and after and analysing the wave form afterwards (sad old Musket) I can say with confidence that the seeming increase in richness of tone as a bonus seems to be borne out.

Chuffed to bits!

The bridge pins are Pinz by name, bought from Strings Direct, about £24.

(I first bought some brass ones from Amazon for £2.95. Took three weeks from China and once I got them decided to buff off the awful gold paint. I felt and looked a right prat when it revealed monkey metal cheap steel!!!)
