Acoustic instruments are made to play using their own natural sound. For many acoustic guitar players, finding a guitar with 'that sound' is a wonderful, satisfying quest—but it doesn't stop there! Many take the next logical step to amplify. A common way to accomplish this is to mic it through a public address (PA) system. Another method is to use an electric guitar amp—but a big problem comes up—where's that great sound? The 'voice' of the acoustic guitar, with its sweet sounding complexities, gets lost. Instead, it sounds more like a roll-call of notes, jumping off the speaker cone, clamoring for airspace on a single wave of sound. It's a very one-dimensional sound. And so, the quest continues...
Sound equipment manufacturers are trying to answer the call by currently producing new amplifiers, pick-ups, microphones, and effects—all geared to get 'that acoustic sound' back. Musicians and distributors are joining in with their expertise to get right combination of gear, using special effects—still the same questions persists, “Where's MY sound? Why can't I make it sound better?” In some cases, musicians are frantic for answers and are spending thousands of dollars with little improvement.
Musicians know there's something wrong, they're trying to dial in their sound—but can't. Their trying to match the volume of the band with them—but can't without the sound going south. The sound guys know the mix they want—but can't get, because of ongoing fight between quality sound with a microphone and feedback by going through the PA. There is good reason for all this frustration—today's acoustic amps are missing a whole swath of sound! It could be that a full 50 to 75% of it is just not there.
Let's solve the problem. First question is, how does a guitar work? Next, what elements of it, are today's amps / cabinets reproducing? That answer is just one...1) the strings vibrating out in front of the sound hole.
This invention (Patent Pending) adds the 3 other elements that are missing from ALL OTHER cabinets and mixes them correctly. 2) The string vibrations going into the resonating body. 3) The saddle / soundboard vibrations coming from inside the resonating body, and 4) The saddle / soundboard vibrations coming off the top of the soundboard. No's. 2 & 3 come out of the cabinet to mix with no. 1 and they all mix with no.4 making very sweet sounding music.
Finally, an acoustic guitar cabinet that amplifies the full and natural sound of your acoustic guitar or violin--this is what we as musicians wanted in the first place!
