Many guitar makers have a policy that any modification to the guitar will void the warranty, inc. adding a strap button. However the notion that properly adding a strap button to the heel of the neck will alter tone, weaken the neck, etc., etc. is absolute nonsense. Plus, for Washburn to make disparaging remarks about Taylor and martin because some of there guitars (not all however) come from the factory w/ a strap button is WAY out of line. Shame on them.
