Eventide - GTR4000 Ultra Harmonizer - Battery

New Replacement Battery Module
Compatible with: Eventide GTR4000
Replaces Part Number: 202106

This module integrates both the battery and memory chip into a single unit. The battery is not replaceable on its own—replacing the entire chip is required.

If you're familiar with removing and installing EPROM chips, you can easily replace this module. First, disconnect the power leads, then carefully remove the old chip and install the new one.

⚠️ Important: Replacing the memory chip will erase all User Presets and Setup data. Be sure to back up your data via MIDI to a Mac or PC before proceeding, as detailed in the user manual.
