Empirical Labs EL8-XS Distressor

No updatable firmware on the Empirical Labs EL8-XS Distressor

It is analog or fixed-function hardware, so there is nothing to update.

You can still add it to your rig to keep an inventory and track its used market price.

Digitally-controlled analog compressor — digital circuits select analog signal paths, but no user-accessible firmware updates. Pure analog signal path.
