Design process - Seeing the guitar through time.

I design each Andre instrument as a unique piece. Some templates come back, but the person for whom the guitar is intended is different every time.

I do understand the investment required to acquire my work. For this, I have developed characteristics that ensure my instruments stand the test of time. (More on this below!)


For too long the guitar has been seen as a disposable object, and my use of cutting-edge materials, whether it's just the glue I use, is as important as the shape or the color of the guitar I build.


Making a custom-made instrument certainly involves a human factor. This is how I approach the work. Your memory of me must be absolutely top ++!   And for that, I objectively take care of the design of your guitar, so that it remains stable through its years of use and ultimately becomes your favorite tool of expression.

Hollow-body guitars 

Kouai hollow-body guitar 2014 Thierry Andre Instruments

My hollowbody electric guitars are thought out in terms of acoustic engineering, before any amplification factor comes into play. They have to sound naturally good on their own to sound great through an amp.

A guitar such as Kouai has great unplugged qualities that one can hear when well recorded.

Acoustic Instruments 

Inside the box to the Maya Bass, can be seen my typical laminated -neck wings- support attached from its neck block to its sides, at waist. The neck wings (as per Steve Klein) offer a stable neck-body connection that prevents the to often needed neck-reset on acoustic guitars.

The acoustic influence of the -neck wings- can actually be heard. Here revealed is a soundboard that is truly put into motion. 

Since neck stability is now present in all axes, the guitar's string energy is directed more towards the bridge.


As seen below, these neck-wings are present in all my acoustic instruments.

In Short:

The design of your instrument can be influenced by several currents and era of the guitar.


It's my job to listen to you, then combine your requests into a cohesive, concise and technically accurate whole:


- From eliminating common pain points, to bringing in new sounds and brilliant functional factors, guitar design is a powerful creative tool capable of enhancing one's musical vision. 

It will be my pleasure to identify and define with you the essential qualities for your next guitar.
