I play all around the neck, see how comfortable it can be for me to finger the the lower registers (The main riff for For Whom The Bell Tolls is a nice worker for that), I see how well it can do in the mid register (The Bass interlude in Orion is a nice example, also for clean fingering), I see how well it can do in the higher register (especially faster played), which Anesthesia, the solo from Ytse Jam, and random tapping and stuff is good for. I also see how good it is for picking and chords, which Tool (Either Sober or Schism's intro) is good for. Then I throw it across the room to see how durable it is.
