I'm happy the only reason to buy the old version is, potentially, the look in a particular Lyr this or Freya that, with this or that finish in certain lighting, etc. And not, any sonic changes I would simply have to check out.Looks like my flat top LISST's (2 for MJ2 and 1 for LYR3) are now collectibles.
Happily, metal 6j5's are too scarce to bother.
