Alerts and Warnings

Our products are not affiliated with or authorized by DigiTech

If your DigiTech GSP21 guitar signal processor comes from a device which runs on multiple batteries, make sure to replace all of them at the same time or you will dramatically reduce the lifespan of the new batteries by mixing them with older batteries.

You have to install your replacement DigiTech GSP21 guitar signal processor batteries in the same original configuration they came out and are required to use your existing hardware and cables to reconnect the replacement batteries when applicable.

It is your responsibility to verify the battery or batteries being ordered match the DigiTech GSP21 guitar signal processor specifications prior to placing your order. Please check your:

  • existing battery dimensions (Length x Width x Height)
  • quantity needed to replace all batteries
