Hexaphonic Guitar Amplifier With Six-Channel String Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guitar amplifiers fail to produce clear note separation and orchestral sounds when playing chords due to distorted signals, limiting the type of music that can be played and altering the natural sound nuances of the guitar.
Innovation Solution
A hexaphonic amplification system with six channels routing sound to individual speakers within a hexagon-shaped cabinet, allowing independent amplification of each guitar string, mimicking the sound of a hexaphonic guitar synthesizer without altering the natural tone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional guitar amplifiers use distorted signals to produce power and sustain, then the sound has power and sustain, but note separation and clarity between strings deteriorates
Solution Approach 1:
The patent divides the guitar signal into six separate monophonic channels, one for each string. Each channel is amplified independently through its own amplifier and routed to a dedicated speaker position, allowing clear separation of individual notes while maintaining overall power and sustain through the combined output.
2Manufacturing precision
If guitar synthesizers use hexaphonic pickups and fuzz circuits to improve note separation, then clarity between strings improves, but natural sound nuances and dynamics are altered
Solution Approach 1:
The patent applies different processing qualities to different parts of the signal. Each string channel can have its own amplifier characteristics and speaker positioning, allowing natural tone preservation while achieving note separation through spatial distribution rather than uniform signal processing.
Solution Approach 2:
The patent replaces electronic signal processing (fuzz circuits) with a physical/spatial system using six separate amplifier channels and strategically positioned speakers to achieve note separation, thereby preserving natural sound characteristics while improving clarity.
3Device complexity
If conventional amplifiers use single or stereo channels, then device complexity is low, but orchestral sound production capability deteriorates
Solution Approach 1:
The patent creates a multi-functional amplifier system where six independent monophonic channels can handle various guitar techniques (single notes, chords, harmonics) and produce orchestral textures. The system maintains flexibility for different playing styles while expanding sound production capabilities beyond conventional amplifiers.

AI summary
A six channel guitar amplifier and speaker cabinet for producing orchestral guitar sounds and of the type having a hexagon shaped cabinet which will house six speakers (14) which will mount to six floating baffle boards (14a) which communicate at the six points of the hexagon cabinet and will vibrate independently. In addition a guitar with a hexaphonic pickup (16) will be received by a six way splitter box (18) through a seven pin cable (18b) and will feed the hexaphonic pickup signal into a six channel preamp (10a) to boost the weak signal inherent in hex pickups. The six channel hex preamp will feed into the six separate guitar amps (12) with six conventional patch cords (not shown). The six separate guitar amps outputs (12a) will be connected to the six speakers through conventional speaker cables facilitating independent amplification for each guitar string, resulting in hexaphonic guitar sound.
