AB - I personally use all of your preset packs, except for the bass (which I may use in the future).
I like to be able to differentiate between the LiveGold, Naked Amps and Plus presets, as I sometimes have all three versions of an amp setup in my available presets.
I'd suggest something like xxx-L2025, xxx-N2025, and xxx+2025 in the prefixes, to differentiate between the setups (similar to the -cx3 you've been using, but a couple of characters shorter.) I'd prefer a modifier to indicate which preset pack it is from. I sort my presets more or less by amp models, and it's helpful to know whether it's a LiveGold or Naked Amps format of preset, since one is more effected than the other, typically.
