The Workshop

Okto Atelier

In addition to making guitars, I also created a repair shop in 2018 that I run with my friend, Merlin Monsieur. I welcome you for the guitar and bass while Merlin takes care of the wind instruments.


It's in my repair shop, Okto, that I repair, maintain and take care of your instruments.

Responsible and innovative making

Despite the fact that they are now protected and their trade is restricted for ecological purposes, tropical timber remains the most poached species in the world.

Traditionally, guitar maker used these so-called exotic woods, more famous than their European counterparts. However, the "Leonardo Project Guitar Research"¹ has deconstruct preconceptions around the higher properties traditionally lent to tropical timber. In a series of studies between 2014 and 2017, carried out in double-blind with more than a hundred participants, the Leonardo Project has shown that there is no qualitative difference between the sound of exotic wood and European wood.

In light of this research and the environmental impacts associated with the use of tropical wood, I believe that our practices must evolve with contemporary ecological and social issues.

I therefore commit to create instruments from local and/or renewable sources. The species that I use are from European origin: my regular wood supplier, Delta bois, located in Grenoble, regularly supplies me with wood that I select for their qualities both structural and aesthetic, according to criteria of wood curating and cutting method.




The wood, heart of the instrument, is in guitar making cut specifically to get the best stability and structural qualities. Before arriving on my workbench, it is naturally dried for at least ten years.

For the front I mainly use Engelmann. It is one of the material with the best ratio between its rigidity and its mass. It allows me to create front that are very light and able to withstand the tension created by the strings.

For the back, sides and neck, I use a selection of woods naturally found in our regions: olive, walnut, maple, apple, ash-olive, poplar, acacia ...

For the back, I will favor softer and less dense species to maximize the depth and bass. For the necks, I will prefer dense species, to support my adjustable neck system and ensure it stability over time.

Carbon fibre and Nomex

Carbon is a fairly recent composite material. Its properties are particularly interesting, combining both lightness and resistance. I use it to reinforce certain structural parts of the instrument, such as the bridge or the bracings. Its incorporation into the skeleton of the guitar makes it lighter than “traditional” guitars, and more sensitive to the strings. 

On the other hand, the nomex is surprising by its shape resembling the cells of a beehive. Composed of synthetic fibers cousins ​​of Kevlar. It is, like carbon, very flexible, light and durable over time. This makes them exceptional materials, particularly popular in the aerospace industry. Placed between two sheets of wood, “sandwiched”, the nomex considerably lightens the structure of the guitar while giving it a lot of rigidity.


The 21 rue sylvabelle

It was at twenty-one rue Sylvabelle in Marseille that we found refuge after our flood in July 2019. It was once a "hôtel particulier" of an earl. We moved in the left side of the ground floor, the former libraries.

You will find Merlin and me, Him to take care of you wind instrument and me for the plucked string instrument.

The Makers

Merlin & Manu

The oKtopus is a metaphor illustrating the diversity of talents coming together in the workshop. Our specialities in terms of instrument and our expertise in our respective fields allow us to adapt to the demands of different musicians.
