Interactive Luthier Analysis Tools
Acoustic Guitar Tone Profiler
The Acoustic Guitar Tone Profiler is a proprietary design tool developed to visually plots your guitar’s core mechanics – Equivalent Mass and Equivalent Stiffness – over empirically validated optimal ranges, for different playing styles and tone profiles.
Instantly visualize the fundamental acoustic character of any guitar design.
Target specific tone profiles (Jazz, Bluegrass, etc.) defined by transparent elliptical zones.
Analyze the physics behind the sound, guided by Frequency Isolines.
4-DOF Acoustic Guitar Simulator
Explore the core physics of an acoustic guitar. This 4-Degree-of-Freedom model, based on the research of master luthier Trevor Gore, lets you instantly see how changing physical parameters—like top mass, soundhole size, or body stiffness—alters the instrument’s fundamental resonances and overall frequency response. Explore the Q factor and side stiffness influence on the guitar’s performance, and save the configurations or curves you want to keep in your library. A truly unique tool.
Flexural Rigidity (EI) Calculator
Explore how bracing affects soundboard stiffness. This tool calculates the Flexural Rigidity (EI) for a specific cross-section of a guitar top. Adjust the soundboard’s dimensions and material properties, along with the shape, size, and quantity of braces. Visualize the section and instantly see the impact on stiffness EI and the neutral axis location.
Bridge and Saddle forces Calculator
This tool calculates the critical forces that guitar strings exert on the bridge and saddle. It models both the constant static forces (like the downward pressure and rotational torque) and the peak dynamic forces (the vibrations from a pluck) that drive the soundboard to create sound.
Resonators Interaction Simulator
See how different resonances combine to create a complex sound. This tool models the interaction of up to three separate resonators. Adjust the frequency, amplitude, and phase of each to visualize how they sum together to create the final acoustic output.
Single Resonator Response Simulator
Master the foundational physics of vibration. This tool demonstrates how a single mechanical resonator’s frequency response is defined by its three core properties: mass, stiffness, and damping. An essential starting point for understanding guitar acoustics.
Mechanical Impedance Simulator
Visualize how sound waves travel, reflect, and transmit between different materials. This tool models wave behavior at the boundary of two media, letting you adjust the density and stiffness of each to see the resulting wave in real-time.
Standing Wave Simulator
Explore how standing waves (modes) are formed inside a guitar body or string. This simulator shows how an “incident” wave and a “reflected” wave combine to create a stable resulting wave, the basis for all musical resonance.
String Harmonic Simulator
Understand how you create a specific “color” of sound just by plucking a string. This tool demonstrates how the pluck position, amplitude, and scale length directly influence the strength and content of the harmonic overtone series.
