Independent shopping perspective
The Korena take
The Extra Blue Ernie Ball rubber strap block keeps a strap attached through an existing strap button. Made from flexible, durable rubber, it slips into place over the button and provides a tight connection without changing the guitar. Its fit is specified for most strap-button types, making it useful when you want added strap security while keeping the current hardware in place.
Strong match
Who this is for

- Using a blue strap block on guitars with compatible common strap-button types.
Consider the trade-offs
When to look elsewhere
