🎹 Boston GP-178 Grand Piano

San Mateo Grand Opening Exclusive

Designed by Steinway & Sons, the Boston GP-178 delivers the tone, touch, and musical depth serious pianists are looking for—without the Steinway price tag.

This is the sweet spot:

A 5’10” grand that gives you real power, clarity, and control, yet still fits perfectly in a home or studio.

✨ Why This Piano Stands Out

🎵 Rich, balanced tone — warm bass, singing treble

🎹 Butter-smooth action — effortless control, highly responsive

🏛️ Steinway-designed scale — proven performance and reliability

🌟 Excellent condition — clean, well-maintained, ready to play
