In absolutely beautiful condition and collector owned. You’ll be hard pressed to find a cleaner example. Frets have their full life ahead of them.

A bold statement in modern boutique guitar design, this 2024 Frank Hartung Caligo showcases the German luthier’s unmistakable vision — sculptural, minimalist, and uncompromisingly precise. Built in March 2024, this example pairs a stealthy graphite finish with a striking indigo-blue curly maple upper horn, creating a dramatic contrast that is both futuristic and elegant.

The red alder body provides a balanced tonal foundation with excellent resonance and sustain, while the stained curly maple neck offers stability and snap. An ebony fingerboard enhances articulation and note definition, complementing the instrument’s extended 25.8″ scale length, which delivers a slightly tighter feel, increased clarity, and impressive string separation across the entire register.

Frank Hartung’s proprietary Caligo Sonic Drive pickups supply a wide tonal palette, from clean, detailed textures to powerful, focused drive tones, all while maintaining remarkable clarity. The minimalist control layout keeps the signal path pure and the playing experience intuitive.

A fixed ebony Caligo bridge with graphite saddles ensures exceptional sustain, precise intonation, and direct energy transfer, while Schaller locking tuners and stainless hardware provide rock-solid tuning stability and durability. Every detail reflects Hartung’s philosophy of functional elegance and uncompromising craftsmanship.

Weighing in at just 7 lbs. 10 oz., this Caligo is comfortable on the shoulder while retaining a solid, authoritative feel. It is an exceptional instrument for players and collectors seeking something truly distinctive — a high-performance boutique guitar that stands apart from conventional designs both visually and sonically.
