Sustainable & fair sound art

…is the guiding concept at soul-guitars.

We live and love guitars, wood, music and people and believe that everyone (including soul guitars ;-) can contribute to a better world.

Repairing, lending or designing your own, lovingly coordinated instrument with the new components of ecology and sustainability?

In instrument making, we work with woods from all over the world due to the acoustics. Origin and forestry play a big role both for the ecological footprint of your guitar and for the local people.
It is a particular concern of ours to manufacture our instruments with woods from sustainable forestry and to build them very carefully into a long-lasting companion for you.

For us, your guitar is not a disposable item but rather a unique companion – your soulmate – on your musical journey!

… and now enjoy reading on!

best regards


… do you already have your guitar soulmate at home? Or does it not even exist yet?

We offer you…


Plum or Ziricote

Difficult question, because they are two different woods, with different acoustic properties and different great visual appeal.

Both floor woods really appealed to my customer, during the wood selection in the workshop. Which one should he now use for his Soulmate.
Actually, he prefers plum, but maybe the ziricote!

So that he can really make a good decision, I offered him to make two identical instruments with the two selected woods.
