The Electro-Harmonix KEY9 Electric Piano Machine transforms the tone of your guitar or keyboard. With 9 presets carefully crafted to emulate classic Wurlitzer and Rhodes sounds, plus more, you can transform your axe and lay down a cool "Riders on the Storm" style groove or some hot funk ala "What’d I Say!"

Each preset lets you control the fundamental parameters that help define that instrument's sound. Many include adjustable modulation like tremolo, phaser and chorus. Use the KEY9 with the B9 and C9 Organ Machines to create your own powerful keyboard rig!

The KEY9 has fast and flawless tracking. Since it uses the sound from your guitar there's no triggering to ruin the feel. It plays and responds just like your guitar - because it IS your guitar.

Take it from EHX founder and president Mike Matthews who says: "You'll dig the way the KEY9 turns you into a Rhodes Scholar!"

  • EHX 9.6DC -200 PSU included

It is hard to believe how well this pedal tracks. It seamlessly follows your guitar and puts out real sounding tone! This takes your guitar and transforms it into an electric piano without anything more than a regular guitar cable. It has 9 different options ranging from 88 Key Piano to Steel Drums and a lot of stops in between. This pedal is especially fun for song writers. It is easy to come up with new ideas while playing your same old guitar! This is a real hands on product review from Zak at Sam Ash Lombard.

Awesome Effect Pedal


What a cool pedal, where your guitar becomes a keyboard. Great keyboard sounds, outstanding tone. Easy to use both in a live setting and in the studio. It has 9 presets.

Amazing Pedal!


My Learning Center office at Sam Ash Indy is right outside the electric guitar department, and I hear a lot of jamming throughout the day. One day I'm hearing organ sounds, and I know there's no organ out there that I'd hear. So I head out, and there's a cat jamming with this pedal...and I was thoroughly convinced it was the real deal. I checked it out further on my own and it's incredible, the best simulator pedal I think I've ever heard. This would be perfect for that guitarist in a band that wants to do keyboard based songs but doesn't have a keyboard player. Highly recommend.

the key you need.


If you a fan of the Wulitzer or Rhodes keyboard your gonna love this pedal. With it's preset sounds you can achive that old school sound with your keyboard and with your guitar. Move over Doors here come you ready to create and innovate.

Electro Harmonix really did great with this guy. Sound quality is amazing and the presets really transform your keyboard/guitar etc.. to give you unique sounds.The organ emulations are incredible making this great for playing out live or for recording to get that unique rhodes/wurlitzer sound. I love this thing!!!

Oh Boy oh boy!!!


Heres another great invention from the insane mind of Mike Mathews! Perfect tracking and outstanding sound. I wouldn't say a bad word about it. This pedal just nails the keyboard sounds you want without having to install a midi pickup or do any crazy mods. Don't pass this up its unreal!!!

Okay, so we understand that you can plug in your guitar and get really amazing e-piano sounds like Rhodes and whatnot. And I've done it, very cool. However, my ears really perked up when pairing it with a synth! Play with the transients and add this baby into your signal flow and get ready to come up with super unique tones!

Awesome pedal


Great pedal. Lets you turn your guitar into a classic keyboard. 9 different classic keyboard presets. Great for fans of classic, vintage music.

High Quality Pedal!


This is the best pedal out there for keyboard sounds. They sound authentic and EHX always makes a good durable product. I've seen this used for guitars and keyboards and the both sound great.



So much in one box


Electro-Harmonix has become one of the best pedal companies out there and KEY9 proves it. Thousands of dollars in classic piano sounds for around $200. Amazing sound and tone. Hours of endless fun in this one pedal alone.
