Authentic ASPRI Professional Series

ASPRI Professional Series

ASPRI Professional delivers inspiration-grade ambience with maximum immediacy and expressiveness. It converts string energy into acoustic space through a fully analog resonance path that preserves intent, dynamics, and articulation at every touchpoint.

System architecture

1) Source capture: StringDrive™
StringDrive™ couples directly to the string vibration path to harvest the most information-rich signal: raw oscillation and transient attack. The capture preserves micro-dynamics and articulation, so the ambience tracks the player’s intent in real time.

2) Analog resonance engine
Captured energy excites an analog resonator that generates a dense repeat structure plus decay. The perceptual result combines early-reflection character with a tail that blooms, reading as reverb and delay simultaneously.

3) Acoustic amplification and blending through the guitar body
The guitar body acts as the acoustic integrator, amplifying, filtering, and blending resonant output with the dry tone. The ambience shares the instrument’s natural frequency contour and projection, so the effect stays unified and dimensional.

4) Perceptual result: “spirit” as a sonic attribute
Space, bloom, and sustain shape how listeners perceive “spirit.” ASPRI strengthens all three through physical resonance that responds to touch, keeping the room feel alive, expressive, and performance-driven.
