  • Awesome review thank you ! Watched and reviews but your video is really helping me making my decision.

  • Strumming a guitar is basically the same as playing arpeggios on a piano. I like that you don’t need a special pickup, but aren’t these sounds so basic? These are the standard instruments and sounds a cheap Casio keyboard has and the free sounds you get with the native GarageBand app on your phone. I’m a proponent of having a guitar solution to convert your sound to a synth or piano, but is this the best we can do?

  • I bought one years ago, very difficult to get sounds like all the YouTube demos. A bit of fun was all, glad I was able to sell it only losing £20

  • These pedals are 100% worthless ; 240 Euro and after a few months , the organ type selector goes crazy . It becomes a game of chance to select the organ you want . Sad …

  • Great demo! I have trouble with this pedal. I use it with a Pog to create organ. Difficult pedals yield wonderful rewards. Right hand muting with extreme settings is pretty cool.

  • Tried this out in a shop. First with a bass, it doesn't handle bassy notes well. With guitar you really have to hit it hard to get any response. Great as a modulation pedal, but I'm not really hearing "Keys".

  • I'm still trying to figure out how the 9 series work. Is it sample based? Or does it model the audio?
    What' the technology behind it? Does it pitch-track, and re-synthesise the audio? Or does it model the initial incoming audio?

  • You need to download the manual and use the settings for each of the instruments. It's not a plug and play pedal. Also, as he says, you need to alter your playing style to get it to sound like a keyboard. A good reverb unit is needed too. I bought mine used maybe the manual is included if you buy it new.

  • Cool playing, so non-showy, appreciated in the world of supergeezers on full display, just love your chord-work, my kind of voicings every time…. & btw the pedal ain't bad. GR8 REVIEW

  • Strange guitar playing. (Not musical to my ears). And not what a keyboardist would play either. The key is to adapt your playing to what sound you are dealing with. Just an idea…

  • Damn dude – I knew you were good, then you wait until the end to do the sweeps so effortlessly… Nice demo.

  • I have watched a few other demos of this peddle and it seems like all have been finger picking rather than strumming. I'm wondering if it's just as good only strumming.

  • This pedal looks better than Mel 9, I should listen to both. I really would like to try them. Though mel 9 has cello and high choir, that is so coool. If I could buy a pedal to make a low choir to simulate gregorian chants, that would be great. After all there is a miku pedal (or whatever)

  • I've had a Roland GR33 for about 10 years, and I just use it in my home studio.  My Roland is great for bass, sax, trumpet, and banjo.  The piano, and organ sounds don't even come close to the EHX Key9.  My Roland "hiccups" on the keyboard sounds.  I'm sold on this baby!
