My understanding is that there are two ways to produce an LP profile:
- From scratch when creating a new profile; or
- By converting an existing profile where the original settings for the profile are known.
As vendors begin selling LP packs, I think it would be useful (and fair) if they clearly stated which of the two methods was used. If the purpose of this upgrade from Kemper is for the profiles to react more authentically to changes in the tone/gain section, then I wouldn't want to end up buying any profiles produced by method 2 where the vendors didn't keep a full record of original settings, but bolted on LP nevertheless.
There is the argument - if it sounds good, it is good; however, I don't want to buy the same profiles I have bought previously from a vendor that they have revamped to be LP, but not completely accurately.
Whilst not trying to cast aspersions, there could be a temptation for a vendor to revamp all their existing profiles to LP (without having to re-profile any amps) as the market moves to wanting LP profiles only, but fudging things a bit as the full original settings are not known.
Furthermore, if there is now a new preferred way to profile (I've seen people mention 'at max gain'), then even if the full settings were known (enabling method 2 to be used properly), if the amp wasn't profiled at full gain originally, the resulting LP profile will be sub optimal compared to an LP profile produced correctly under method 1.
