Arnold; "This stuff in the above post about semi-permiable glue joints and 71% less likely to get out of tune" This is not what Jim said/paraphrased, what he did say was-- " "71% less responsive than traditional spruce plank soundboards to ambient humidity changes" " While I agree about your conclusions, I also know that Jim D. is a good enough tech not to have meant 71%....out of tune. Even a slight change in soundboard geometry will cause a change in the tuning of any instrument, and ambient temperature/humidity changes are the major reasons for this. The only good reason for laminated boards IMHO is that they are much less likely to split or crack and in all other repects are inferior to solid boards. Jim Bryant (FL)
