[CAUT] Polishing Agraffes

[David Love]

One light turn with one of those little reamers and I've never had a noise
problem with new agraffes and without going through the whole polishing
routine.  In this case I'd probably opt for new just because it's easier and
new agraffes aren't that expensive when you consider the labor of the
polishing process to remove string grooves and discoloration and such.  Give
them a quick shot of some lacquer for brass and they'll stay looking nice
for much longer.   Whenever I change bass strings I just make it a habit of
changing the agraffes.

Since the agraffes are out, don't fool with them. Put in new ones. You'll
get a better termination.

Can you provide some proof of that statement? I'd love to see it. :-)
