This latest model of acoustic bass presents developments arising from my research on acoustic guitars, steel or nylon strings, prestressed bracing, double sound holes. It is equipped with an electro-acoustic system I chose for its highacoustic fidelity, the French brand AirBagC from Ischell.

Mahogany back and sides, spruce top, mahogany neck, ebony fingerboard and bridge, Savarez nylon strings, scale 860mm, weight : 1,8kg

This acoustic bass is the model I made in the 90s.
I have built a number of them, in 4, 5, and even a 6 strings.
I was already using local woods at that time, such as ash,
Walnut or cherry for bottom and sides.

This one is one of the first, it dates from 1991 - spruce top, cherry wood body, mahogany neck and ebony touch 2 octaves.

This bass 6 strings is a unique piece, made of European wood custom for its "happy owner", which I publish here a message satisfied and more than satisfactory for me ...


Hi Fred,

Simply perfect. In fact it started on Saturday evening. I plug in, I play, emmanuelle (my wife) arrives with big eyes and tells me that she finds the sound fantastic. In addition to finding the bass beautifully beautiful and being fascinated by the quality of manufacturing, details, woods ...

Monday evening the same wonder of my pianist. The latter works in musical editions for which he sometimes directs studio sessions. He has a big ear. What strikes us first is the clarity of the note and this on the whole register of the neck, from the lowest note to the highest. Nothing drools in the bass, nothing attacks in the treble.

Then what strikes us is the naturalness of the sound. It is magnificent on the solos (very close to the sound of a Steve swallow while playing the pick) and super efficient and beautiful in accompaniment. Emmanuel the pianist (I’m surrounded by Emmanuelle…) told me how much he enjoyed listening to the instrument, the sound touched him. The unions are fantastic.

Well, I still have a lot of work to master the tool. After a good ten hours spent on it I realize how possible the variations of games are.

Really like an acoustic. I discover all the manufacturing details with immense pleasure.

Brief BRAVO. See you next time. Fred and thank you again for a fantastic job. E.L.
