    1. Chick, the online manual says 10 milliseconds latency. However, as this piece of kit isn’t available yet, I would not trust that figure until some benchmarks have been performed. The site & manual is a little vague on a lot of areas, and the troubleshooting section is 2 empty pages!

  1. Mixed emotions.

    On one hand, that demo was not-for-me (let’s just say). I do like the guitar’s shape and general aesthetic. 10ms latency isn’t too bad.

    I’m not convinced that they have a quality guitar there. (They might ?) What might convince me is if they mentioned who designed & built the guitar & electronics.

    The ONLY think that could convince me to buy a rig like that is if the guitar is really excellent sans the MIDI stuff. That probably would price it out of my range.

  2. I really dislike these product videos where the camera cuts away from the instrument just as one is beginning to assess an interesting feature, or examine a detail of the instrument. Instead, I am left with visions of some dude grokking his rock-out and a lot of ramp wave buzzsaw noises lingering in the room like an unpleasant odor. Think I’ll pass on this one, because I can’t rightly get behind what it’s actually doing.

  3. If people really want to know how this instrument works, they can go to the website and learn more. It includes the user manual. To judge the usefulness of an instrument based upon a brief video seems to me to be a very superficial evaluation.

  4. it doesn’t look like it would be a very good GUITAR – it looks like it is hollow plastic with single coil pickups – the sustain has gotta be crap and with additional electronics it has gotta be noisy unless the pickups are shielded separately from the rest. Also the pickup toggle is on the top of the guitar which looks really awkward. Not saying it wouldn’t be serviceable but for the price you can either create or buy better options on the market and I know KMI has stuff in the works too – also the balance bar is kinda goofy

  5. If anyone is attending Moogfest 2016, I will have an Expressiv Midi Guitar at my workshop, The 10 Minute Music Station. Come by and I will give a demo. I look forward to meeting some of you and passing on your thoughts to Rob O’Reilly.

  6. It looks like they stole someone’s dirty coffee table and didn’t bother cleaning it. Also the multiple OH faces are not a good sell for this. Maybe it can be used for Guitar Hero or Rock Band :p

  7. …regarding the demo there’s this thing called a keyboard for that. To my point I haven’t heard much good stuff resulting from MIDI guitars. I think they should make a midi BASS guitar. It makes much more sense with synth textures, do they have a bass guitar too?
