The Electro-Harmonix KEY9 Electric Piano Machine transforms your guitar or keyboard into classic electric piano sounds, including Wurlitzer and Rhodes, plus vibes and steel drums. Unlike sample-based pedals, the KEY9 uses modulation for accurate tracking and no latency, delivering a variety of tones with adjustable modulation effects. This pedal is ideal for live and studio use, offering a robust build and versatile sound options, and is perfect to use in conjunction with the B9 and C9 Organ Machines.
Guitarists praised the KEY9 for its ability to emulate classic electric piano sounds like Rhodes and Wurlitzer, with some finding it versatile enough to be used with synths and other instruments. Users also noted the pedal's robust build and the wide range of sounds available. However, some reviewers found the pedal to be too expensive and noted that the sounds were not all convincing and that there was too much latency between playing and hearing the result.
