Hi Dan, Exactly what I suggested. Energy is stored in the duplex and then released...increasing sustain. It can only act as buffer/filter/storage for energy--it is not struck so it can not create *more* energy--it can only absorb. Thanks for doing the research to prove it. Now if a person used a real time sound analyser...... At 01:47 PM 9/5/02 EDT, you wrote: >Duplex Effect, > >the comment that the duplex "absorbs, bleeds and filters" energy is >interesting.
