I know most of us fall into two camps of straplock users: Dunlops and Schallers. I have and personally prefer the Schallers, but the one thing I do not like too much is that they can often squeak. I have one particular set on one bass that seems to be worse than the others. My question to you Schaller users (and anyone who might know) is: how do you get rid of the squeaking? Do you have a specific favorite lubrication that is not too messy and gets the job done? Any suggestions would be much appreciated.
