Hi Fred, as an addition to my previous post. Remove the felt that's muting the duplex, Lift the strings both, in from and to the rear of the of the forward part of the resonator. Move the strings up scale about the width of a string and, fudge relocate hammers. Another partial solution is to put a small dab of PVCE glue on the string in the forward duplex section. It will reduce the noise, but not kill the detuned duplex. Regards Roger
