“Rev II” Mario Signature

The story of the creation of this model is short and simple. Mario Ivanov contacted me with a request to make a 6-string headless bass for him. A bass he always wanted to have, a bass which could fulfill his mechanical, geometrical and sound criteria, and unleash his fingers and creative mind for making music.

Thank you for trusting me, Mario! Thank you for sharing your intimate connection between you and the bass with me!
