Yamaha GB1 / GB1K Piano: What It's Worth in 2026, Prices & Listings

Size: 5'0" (151 cm) baby grand
Made: Introduced around 2000; the GB1K update is still in production, built in Indonesia

The Yamaha GB1 (and its current version, the GB1K) is Yamaha's entry-level baby grand: a five-foot piano built in Indonesia to hit a price that makes a new grand attainable. It is the smallest grand Yamaha makes and one of the best-selling baby grands in the world.

Used GB1s are common and relatively young, so condition is usually good. Their value is limited by size — a five-foot grand has short bass strings — rather than by quality.

What to know about the Yamaha GB1 / GB1K

The GB1K is a design update of the GB1 with the same size and purpose; both are Indonesian-built.
A five-foot grand will not outperform a good 48-inch upright in bass; it wins on touch, dynamics and looks.
Disklavier (DGB1K) and Silent (SC) variants exist and are common; value the electronics only if they are current and working.
Polished ebony is standard; white and other finishes ask a little more.
