I may want to use that one day.... The tuned duplex--the aliquot system--will affect power and sustain in an inverse relationship. When 'properly' tuned it may increase power--at least it will inhance the illusion of power by increasing the volume of the affected harmonics immediately following hammer impact--but it will reduce sustain time. ddf
