Change the sound - how works the bridghole-tuning at FUNNELbody®-guitars?

The bridghole-tuning is a method to adjust equally the way of frequency at this instruments. This principle is one more decisive step in the development of FUNNELbody®. The principle is simple. By several small soundholes in nearest proximity of the place of vibrations-transmission to the body (string/saddle), a minimal "acoustical short circuit" is produced. The result is that highest portions of frequency are produced at the nearby string. As the soundly character of the resonance body may be, the bridgeholes can be individually closed again with small foam rubber plugs, which anew changes the sound of the instrument. There are innumberable possibilities of closing and leaving-open at the respective strings.

If the holes are closed = warm sound, if open = more clearness.

One more advantage: By the number of bridgeholes the weight of the bridge is reduced, which opposes the suppression. Besides the bridge oscillates more freely, also if all holes would be closed by the plug.

Note, it works insufficient at traditional guitars!
