Taylor AA Battery Box Adapter

Early Taylor guitars equipped with the ES1.1 pickup system used a compact AA battery box that is smaller than the later 9V battery format required by modern onboard preamps. The Taylor AA Battery Box Adapter provides a simple, purpose-built solution that allows these instruments to be upgraded to the Go Acoustic Audio ES Replacement System without permanent modification.

This adapter mounts directly into the original AA battery box opening using a custom-machined adapter plate with an integrated jack. A custom cable assembly connects seamlessly to the ES Replacement System preamp and includes a dedicated 9V battery lead. The supplied battery pouch allows the 9V battery to be securely mounted inside the guitar through the sound hole, preserving the instrument’s structure and appearance.
