1. Bounce the string bed against my palm to feel the tension. - I have no idea what I'm doing, tbh 2. Realign/straighten the strings even though the stringer already did - Attempts to move the strings ever so slightly, only to move them back a second later 3. Look at the string bed from an acute angle - Helps tremendously at finding misaligned strings, and then -> #2 4. Smell the string bed a little - Hmm, does gut have a smell? What else do you guys do?
