How do I determine if my EP001 passive pickup is upgradable such that it can accommodate the new EPS active module?

To evaluate if your guitar’s pickup is the newest upgradeable version, you’ll need to get a mirror and a phone or flashlight to look into the sound hole. Position the mirror so that with the use of a flashlight or phone, you can clearly see the pickup connector on the inside of the guitar. You can even try to just use a cell phone by using the movie function with the light – if the focus is good enough, this will work as well.

The newer upgradeable pickups will have a socket with a 2mm connector that you can remove from the back of the pickup jack. This connector can be removed and re-routed to the active pickup module for upgrade. The picture below shows these as type A (which have no sleeve), and type B (which have a sleeve); both of these can be unplugged and upgraded.

The older non-upgradeable connectors (depicted below as type C) have heat-shrink tube where the connector jack and the 3 wires going to the under-saddle piezos connect. This pickup can’t be upgraded because the wires are soldered directly to the pickup connector
