While changing strings, I had the brilliant idea to condition the fretboard. No sooner than I removed the strings, I heard an odd clunk. Once I realized the bridge wasn't where I expected it to be, I had an absolutely emotional experience. After a moment I sorted out that this was actually ok and began work on getting everything back in order. Several tune up, test, detune, shift, retune cycles later and all is well again. Cheers, TB folks.
