Yamaha DGX-670B 88-Key Weighted Digital Piano - Expressive Home Piano

In this review of the Yamaha DGX-670B, the bottom line is simple: it is a versatile, practice-friendly home digital piano that delivers convincing grand piano tone and a realistic weighted action at a sensible price. The DGX-670B is aimed at beginners who want an authentic playing feel and at hobbyists who want a one-board solution with built-in accompaniment and learning aids. Its strongest reason to buy is the combination of the Grand Piano Sound CFX Stereo Sampling and the gradated Acoustic Piano Touch Weighted keyboard action, which together make playing feel and sound much closer to an acoustic instrument.

Key Features

• Weighted Key Action: The Acoustic Piano Touch action is heavier in the low keys and lighter in the high keys, giving a realistic response that helps build proper technique.
• Grand Piano Tone: CFX Stereo Sampling reproduces the rich, resonant character of Yamaha's flagship grand for more expressive performance.
• Wide Voice Selection: With 630 instrument Voices, players can explore pianos, strings, organs, and synth sounds for varied arrangements and practice.
• Automatic Accompaniment Styles: The 263 Styles provide full-band backing in genres like rock, R&B, and dance to make practice more musical and fun.
• Adaptive Style Accompaniment: Styles shift dynamically with your playing intensity so backing parts react to your touch and note density.
• Included Accessories: The keyboard comes with a music rest, sustain foot switch, and power adapter so you can start playing immediately.

Who It's For

The DGX-670B is a great choice for beginners and intermediate players who want realistic touch and premium piano sound without buying a large acoustic instrument. It suits home practice, small apartment living, and players who enjoy accompanying themselves with built-in styles or using the microphone jack for singing with digital vocal effects.

Players who need a furniture-style stand or a full console look should note the stand and bench are sold separately, and those seeking a stage-focused, lightweight gigging keyboard with extensive routing might prefer a dedicated stage piano or synthesizer instead.

Pros & Cons

Pros
