Amazon affiliate links

As an Amazon Associate, this site earns from qualifying purchases. Some links on this site, primarily in our speaker and gear guide, are affiliate links. If you click one and make a purchase, we may receive a small commission at no additional cost to you.

Affiliate relationships do not determine our recommendations. Products are chosen for how well they work at an actual ballpark, and when a cheaper option is the better fit, we say so.

Our own product

References to the WalkAmp app link to our own product. We built it, we're proud of it, and we recommend it because this entire site exists thanks to years of running walk-up music at youth games.

Privacy

This site does not require accounts, does not collect personal information, and does not run third-party ad trackers. For the WalkAmp app's privacy policy, see walkamp.com/privacy.
