Bass Neck Pocket Options

Warmoth bass parts adhere to Fender's® vintage/original neck-heel and neck-pocket dimensions, except when noted. Many other manufacturers also use these specs, but they are not universal - even among Fender® products. Accurate measurement is the only way to ensure compatibility of parts.
