Used Yamaha CK88 Stage Keyboard

The Yamaha CK88 is a versatile 88-key stage keyboard built for musicians who want convincing piano feel alongside a huge range of piano, electric piano, organ and synth sounds. Its Graded Hammer Standard weighted keyboard, hands-on controls, built-in speakers and compact 13.1 kg design make it equally useful for gigging, rehearsing, teaching, recording and home practice.

This pre-owned example is in Good condition and includes a mains lead. The original box and owner's manual are not included.

What Makes the Yamaha CK88 Special?

The CK88 combines Yamaha's AWM2 sound technology with dedicated organ functionality, giving you 363 Voices and 128-note polyphony in a keyboard designed for fast, hands-on performance. Its weighted GHS action provides a more piano-like response than the smaller CK61, while Live Set memories make it easy to prepare and recall complete performance setups.

Unlike many traditional stage keyboards, the CK88 also includes its own 6W + 6W stereo speaker system, Bluetooth Audio and the ability to operate from batteries. Add audio inputs, MIDI, USB audio/MIDI connectivity and flexible pedal connections, and it becomes a highly adaptable keyboard for both stage and studio use.

Who Is It For?

The Yamaha CK88 is particularly well suited to:

• Gigging keyboard players needing an 88-note weighted instrument

• Pianists who also require organ, synth and electric piano sounds

• Function and covers-band musicians

• Worship and church keyboard players

• Music teachers and rehearsal spaces

• Songwriters and home-studio musicians

• Players wanting built-in speakers for practice

• Keyboardists needing an adaptable MIDI controller

• Musicians who want a portable alternative to a heavier stage piano
