If you play one of our instruments unplugged you can hear it. If you plug it in you can hear it. The bottom line is that no wooden guitar is capable of doing what our guitars do. It’s impossible. It basically comes down to two things. Mechanical Impedance and Paramagnetism.
Mechanical impedance is a measure of how much a structure resists motion when subjected to a harmonic force. A guitar’s mechanical impedance is what determines its ability to sustain a note. Everything about a guitar’s construction, as a whole, will affect this, but builders and players know that the density of material plays the most direct role on the natural sustain of an electric guitar. When you pick a string it vibrates. As the string vibrates some of that energy transfers out of the string into the guitar wherever it is in contact with the string and some of the energy is reflected back into the string. The more the guitar as a whole can resist this process the longer it will sustain. Denser wood supports higher frequencies. Aluminum is far more dense and has much higher resonant frequencies than any wood. That means our bodies are capable of returning much more harmonic content back into the string than any wood guitar is capable of, and the long musical sustain of our guitars is striking and complex.
Aluminum is the Ultimate Tone Material
Our bodies our machined out of solid 6061 aircraft aluminum. A material more than 2x as dense as the hardest tonewoods.
Density in g/cc (grams per cubic centimeter)
African Ebony .76
Indian Ebony .97
African mahogany .66
Indian Mahogany .54
Maple .5 - .67
Rosewood .71 - .78
Another unique trait of our guitars is their harmonically dense sound. It is immediately obvious when playing our instruments unplugged and plugged in. How? Everyone knows aluminum is not magnetic, however few people are aware that aluminum is Paramagnetic. Paramagnetism is a form of magnetism whereby certain materials are attracted by an externally applied magnetic field, and form internal, induced magnetic fields. This property allows our bodies to interact with, and sing through, the magnetic pickups in a way that only aluminum can.
