A guitar can sound decent and still feel like it’s holding you back, which is frustrating because nothing seems “broken.” You play the same riff, yet the attack shifts, chords don’t sit the same, and bends feel stiff one day but strangely slippery the next. That isn’t always your amp or your hands. A lot of it starts where vibration begins, because tension, gauge, and surface feel shape how cleanly a note speaks, how long it hangs, and how steady pitch stays after hard strums.
