I feel like some of you guys are splitting hairs over the strap lock issue. When I got my first Sadowsky, all of my other basses and straps had Schaller locks. I liked the Dunlops better and replaced everything. Both Schaller and Sadowsky locks work and are quality products, it is simply a personal preference and thus replacing the buttons with my preference is a non issue for me. I actually always keep one set of Dunlops in stock, just for the case I buy a new bass that does not come with them. The buttons are $7.49 on Amazon with free one day shipping if you are a member.
