I'm giving serious thought to making the switch to a Kemper for my live playing. As I look for used heads, is there anything that I should look at to "avoid"? Do I need to know what firmware version the head is at? My understanding is they all can be upgraded to the latest/greatest version. Are there any issues with particular years or versions that I should be aware of?
Still going back and forth on whether to get a powered head or a non powered head. Leaning towards "powered" (if I can find the right deal) as I "think" I have more options with how to use it for gigs/practices, etc.
Overall, still in the "gathering info" stage but want to know what to avoid just in case a deal comes up.
