I have new guitar tech.
You know guitarists. They can play cosmic notes, ultra-fast, or very gentle and melancholic, or anything that YOU love. And usually they know nothing about their gear. No, really.
Almost every guitar player has a guitar tech guy behind him. Usually he is other (sometimes very talented) guitar player, with two (crucial) differences:
he did not have enough luck to become a star,
he actually knows the technical stuff behind guitars, effects and amps.
Many years ago my guitar tech told me, he lives dog's life and left. Nowadays I have a dog instead of guitar tech.
