for a sound optimization service on one instrument I will charge you unique

 € 770.

a single treatment will take approximately 4-5 days


after the treatment, I will give a lifetime guarantee on the instrument - not the musician

should it occur that some resonance weaknesses show after a necessary service and/or repair, the fixing treatment, that normally only takes a few hours, will certainly be free of charge.

with kind regards
