November 14, 2025 · 1 sources

Empress Effects lists Echosystem firmware v2.42, dated 2025-11-14, on its Old Firmware Downloads page¹. The page collects earlier firmware for the Echosystem, Reverb, ZOIA and ZOIA Euroburo¹.

The page states its purpose: "These files are provided for users who need to revert to a previous firmware release for compatibility, troubleshooting, or specific workflows"¹. It directs users who simply want to update a pedal to the latest firmware instead¹.

The Echosystem entries listed on the page, with their release dates as given:

The page carries a separate compatibility warning for the ZOIA: "ZOIA firmware version 1.05 and earlier is not compatible with newer ZOIA hardware. If your ZOIA has a serial number of approximately 2000 or higher, do not install firmware version 1.05 or earlier, as it is not compatible with your unit"¹. No such notice is given for the Echosystem.

The page does not describe what changed in v2.42 or in any other Echosystem release, and gives no price or availability information for the pedal itself¹.
