A short term for a guitar tech, drum tech, bass tech, etc. The person who is in charge of tuning the musicians instrument, taking care of it, perhaps operating remote pedals, and so on. The musicians right hand man, when it comes to their gear...basically a step above the average roadie.
John, the guitar players tech, handed him a new guitar inbetween songs.
