  1. I wish such stuff would also be made as normal desktop devices with normal knobs, instead of these floor models with on/off knobs that normally have to be pressed with your feets….

  2. Initially I was thinking of buying these as a duo when the reverb inevitably came out. But after the initial hype, I think it all dried up quite a bit. To me, it seems a bit too deep for hands-on tweaking and perfectioning. I am not a fan of deep editing on pedals, but when it needs to be done, just throw an app at it like Source Audio does… At least I get it over with more quickly. So I guess I’ll be happy to continue to use the Ventris and Nemesis.

    These two Meris pedals, I think, are for people who actually perform, and want to do away with a lot of other pedals and control their song presets via MIDI. With these two pedals you could get everything you need from delays and reverbs. I am more of a pedal collector and I don’t run a pedalboard (due to not being a guitarist) so I chain up new configurations at every session, but these two could clean up a pedalboard and leave plenty of space for tons of other effects that would otherwise be stuffed with different delays and reverbs.

  3. Fascinating sounds, features, and UI. The price seems about right for what it does.

    For a person who really dives into lots of ambient kinds of tones, this seems like a pretty amazing device which brings something new to the table– or perhaps just a new combination of things.

    Having a small display and the full editing UI in the unit is pretty typical of multi-fx– and with a feature set like this, they’ve done a good job of making the “diving” at least kind of fun to look at (cue bubbles).

    I agree that Source Audio’s concept is great (theoretically) — put the basic controls and presets on the pedal, and allow deep editing via app. However, in practice, it isn’t always very tidy– as terms are often inconsistent or vague.

    I’ll give a shout out to Fractal and the FM3, which for not much more dough than this, can give you really nice reverb, excellent amp/cab modeling, great effects, and superb tweakability. Not for the faint at heart, though.

  4. Is it only me or does all new reverbs sound similar?
    It seems they all have some shimmer algorithm that adds harmonics, have reverb tails that last forever, but they all sound super digital, artificial and are really bad at preserving the instruments original timbre.
    I think it’s really only OTO Machines BAM and BIM that I have gelled with lately.
    They have a nice warm sound and you can still hear all the nuances from the original instrument and not just a wall of effects when you use them…
    Where are the reverbs for all of us that are not interested in creating a full ambient composition from one guitar chord only?
    For us that want some more options than your standard plate or room reverb but still want it to sound natural, warm and most importantly enhance the instrument instead of adding a sound of it’s own?
