Sorry for this rookie, pre-sales question:
I am considering buying a used Helix Floor and I'd like to understand how the versioning of the hardware device works. For example, if I find a used "Helix Floor' on Reverb.com, can I assume that they are all the same since the Helix Floor was originally released and that an older one is as good as a newer one? The only difference would be the firmware, which can be upgraded on any unit? I'm just having a hard time understanding what is the latest version of the hardware.
I know the idea of a hardware version is changing, and that you can buy once and benefit from future upgrades via firmware, impulse response packages, etc., but is that completely the case? I just don't want to purchase a legacy hardware device.
