If the 4th string is to be tuned at the same pitch I find that it had better not be flat... better a shade sharp if off at all. But if its tuned at a 5th above I seem to like to let it drift a tad on the flat side if its going to miss. We've talked a bit about backlengths, duplexs, and other sympathetic vibration schemes several times. This one alwasy amazes me at how much it contributes (for better or worse) to the overall sound of the piano. Well worth experimenting around with IMHO RicB
