saved a virzi bros. 3/4 violin from the dumpster...
tone enhancer intact... (two plates) smaller over large. it seems to be a delicate affair, but has lasted to this day.
haven't had a chance to set it up,but you have renewed my interest.
my guess is that it may be effective with the higher pitch of violin,mando,etc,but it may restrict and struggle on the down low.(flowmasters on a cummings?
