Wow, check out this thing! A mini modeling pre-amp that I can feed right to my headphone amp. It sounds pretty good, has a cabinet emulator, and seems to clean up well with volume:

I’m also looking at Two Notes ‘Le Clean’ tube preamp, which is a lot like the Kingsley Jester (or Squire + Page) but has cabinet simulation and is meant to go straight to line out. But many run with an additional cabinet emulator for direct out (just for tone, not for load.)
