Independent professional appraisal service dedicated to vintage basses, with advanced specialization in vintage Fenders and Pre-CBS instruments.
The world of vintage basses is as fascinating as it is complex. Authenticity, originality of parts, historical consistency, state of preservation, refinishing, invisible modifications, real market value: every detail can have a considerable impact on the quality, rarity, and value of an instrument.
Thanks to in-depth experience with high-end vintage instruments and years of analyzing historical basses worldwide, this service allows you to obtain a professional and specialized opinion before a purchase, sale, or private appraisal.
I am Léo Chazallet, a professional bassist and collector specializing in vintage Fenders.
For many years, I have dedicated myself to the study, analysis, and use of historical Fender basses, with particularly developed expertise around vintage Jazz Bass and Precision Bass models.
I have had the opportunity to play, compare, and analyze hundreds of vintage instruments during my international travels, including Fenders produced every year from 1954 through the various Pre-CBS and CBS periods.
I also collect several exceptional Pre-CBS Fender Jazz Basses, selected for their historical, musical, and acoustic qualities.
