Dear fellow techies, Patient: Yamaha GH1, 14 yrs old. Condition: Treble bridge delaminating from soundboard and soundboard delaminating from rib #2 & 3 (approx. C5 - G6). Downbearing barely detectable at all points along bridges. Symptoms: None really! Tone is relatively even throughout the scale, with good sustain. No dead spots, buzzes or rattles. I presented the client with the following options: 1. Do nothing. She enjoys the piano and apart from the obvious untoward appearance, the piano sounds pretty much the way a GH1 normally sounds. 2. Reduce tension across the scale and remove top 3 octaves of strings, use various wedging, clamping, screwing, gluing and or sorcery techniques to reunite the delaminated portions of bridge/soundboard/ribs. The worry here is that this may result in a net reduction in the already barely detectable downbearing. 3. Put newfound soundboard replacement savvy (re: Brandon University/Bolduc soundboard seminar) into practice and slide a new board into place. Anyone ever see this condition on a Yamaha piano before? Anything to add to the above options? Best regards to all! Stan Kroeker Registered Piano Technician
