Big Celtic O

Sweet highs. Deep lows.

WHAT IT IS

The Big Celtic O is a handmade mandolin with a wide-open voice and rich sustain. It blends the warm, sparkling tone of a European oval-hole design with the clarity and depth you want for modern playing on stage, at home, or in the studio.


WHY YOU NEED IT

If you find most F-style mandolins too sharp or tight, this gives you more space in the tone. Fuller lows, sweeter highs, and longer sustain.

It’s slightly warmer than the Big Celtic F, with a bit more natural resonance. The kind of mandolin that rewards light touch and expressive playing, but still holds up when you dig in.


WHAT YOU GET

A fully handmade large bodied oval-hole mandolin.
Wide, open tone with strong low end and clear highs.
Premium tonewoods and expert voicing.
Custom detailing and finish options available.
Comfortable, expressive, and deeply musical.


WHAT MY CIENTS KNOW
