Yamaha upright in a bad location: coke in the middle treble at the upper termination. I was amazed at how dead the sound was. I looked for a bridge separation, even. I used a towel, dish of water, and toothbrush to soak and scrub out what I could. It got back about 1/2 the tone. It would have been better to loosen the strings, pull them aside, and really clean them and the area, but there were too many and not enough time. Avery, my guess is coke fouling the agraffe. Maybe slack off the string, scrub both the contact point of the string and the agraffe hole, dry, pull back up, and see how it goes. Of course, it could have fouled the wrap as well. Susan
