Client just bought a used Kawai EP308. 88-note "grand", conventional action and dampers, no soundboard, piezo-electric pickup under the bridge. Got a good price because there were some broken bass strings. Prior owner's tech tried replacing them with universals, and they broke again. Then the prior owner bought scale data over the internet, had strings custom wound, and they broke. The foregoing history is all hearsay: no written documentation, first-hand accounts, nor physical evidence available. All 3 sets of broken strings (originals, universals, and custom scale) have been lost/discarded. Do these electric pianos have a history of breaking bass strings? Is it safe to specify new strings with characteristics similar to their neighbors, or should I be designing to a lower percent of break strength? The missing strings are E2, F2, A2, C3, and D3. Neighboring notes are at about 60% of breaking strength. thanks Mike
