Northfield NF-ATO1 Octave Mandolin

Northfield NF-ATO1 Octave Mandolin

Italian Spruce & Mahogany
1.4" Nut

Regular price $4,000 Sale Serial AT18075


We've had a handful of these gorgeous Northfield octave mandolins through our shop and have been consistently impressed with their tone, playability, and craftsmanship.

As the name implies, the AT01 is tuned an octave below a standard mandolin. This gives it a warm, open tone with amazing low end and resonance. This is a really fun instrument that's truly in a league of its own.

Includes molded plastic hardshell case with crushed velvet-like interior.
