Musicians cannot replicate their own tone settings across instruments or practice sessions

Musicians spend hours dialing in the perfect tone/sound on their instrument, but when they try to recreate those same settings later or on a different instrument, the result sounds completely different. This frustrates both hobbyists and professionals who need consistency for recordings, performances, and practice. Current solutions fail because tone is influenced by unmeasured variables (technique, environment, instrument condition) that aren't captured in written settings alone.
