  1. A nice audio video prod can make believe many things : high sound quality, no skill required, no overdubbing, low latency …

    Maybe this device should be used to explore new sounds, not for keyboard imitation 🙁

    1. Demos are usually used to illustrate the main “purpose” of the item, it’s up to the users to figure out the crazier, more interesting cases.

  2. Curious whether anybody seeing this has ever run an actual keyboard through one of these EH pedals, like the C9 or the B9, and what your experience was.

    1. not through those – but I use a superego all the time on synths – esp monophonic ones because you can use the left toggle setting (multiple voice) to do some crazy stuff, esp with the gliss

  3. The B9 / C9 / K9 is a great series of really unique pedal. I really hope they do a M9 Mellotron pedal next, that would be awesome (I have emailed them about this in the past as the C9 has one Mellotron flute setting).

    1. mellotron would be perfect.

      the sound is this one is experimental, definitely not a replacement or even decent emulation really, but a neat couple sounds for guitar. Maybe shoulda tried it with more distortion to get a realer EP sound?

  4. Ignoring what it’s intended to do, that’s a lot of sonic wiggle room for 200 bucks. Would like to hear synths and drum machines through it.

  5. Nice. Since this thing is seemingly tracking so well, it would be fantastic if they made a version with a MDI out so one could use their favorite synths/sampler.

  6. Even when you imitate Bob James, it still sounds like a guitar. Agree that this is better for unique new music rather than trying to cover the keys on Rider On The Storm.

  7. As with synths, it depends on how large your head is on the inside. I’m glad I can already play the piano or I’d be “jealous.” Talk about a killer Xmas gift. I like the Mellotron idea. If they added a brass pedal as good as the organ and piano models, someone could become a scary one-man-band pedalmeister. Its a bit funny for me. I have one friend who will only use reverb and sees the guitar as “pure.” Another is physically screwing with a couple of guitars so they’ll naturally play in alternate tunings. I wish I had one more like Michael Brook, a guitar whiz who uses effects quite well. If I was a guitarist, I’d be covered up in EH pedals instead of plug-ins. 😛 Check out this track. This kind of quality is what I’m always hoping for. Its simple, but it has muscle & a bit of mystery to it.
