The Custom Series

Beyond the standard. Built for the individual.

A Few Examples from the Custom Series

Every Osthoff guitar is individually handcrafted, but the Custom Series is where John explores ideas beyond the standard models—alternative body shapes, unique cutaways, baritones, and more—while maintaining the same structural integrity and refined craftsmanship found across all his instruments.

The Custom Series

If you can imagine it, we can build it.

The Custom Series is where John’s craft becomes a true collaboration. These instruments begin with the same structural integrity, voicing philosophy, and aesthetic discipline found across his standard models, but the design process opens up to explore ideas that fall outside traditional outlines and configurations. Whether it’s a unique body shape, a specialized tonal goal, or a one‑off concept, each Custom Series guitar is shaped through thoughtful conversation and a shared sense of purpose.

While certain requests may influence the final pricing, John works closely with each player to keep the project grounded, musically meaningful, and structurally sound. The goal is simple: to create an instrument that feels deeply personal, plays effortlessly, and reflects the creative partnership between builder and musician.
