Also, while we're on the subject... I use the Strymon Deco and BlueSky. Next on my list are the Ola and Flint. Also use a TC Electronic Helix.
Deco:
Can only recommend this pedal!! Stereo in / out. Wonderful tape saturation. VERY different sound from the Pro2's distortion and girth. Also does a very decent chorus (though I often wish is could be "wetter". Simple but sweet tape delay (one or two repeats). Not enough for intricate delays, but very nice to thicken the sound, great slap, and widening of stereo image. I'd say the Deco is my favorite synth pedal bar none. So flexible and great tone. Also should mention that Strymon pedals are superbly suited for synths: not only are they stereo in and out, and have expression inputs, but they take line level signals brilliantly.
BlueSky:
Obviously not as powerful as the BigSky, but still very nice. Not super happy with the room tone, to be honest. A bit dark and muddy for synths. Shimmer is great, but even with zero pre-delay is a bit slow to kick in. For shorter sounds the wet level needs to be set very high to even hear the shimmer. Not always appropriate. Favorite setting is the plate, either in natural or mod mode. Very smooth, bright but full and not harsh, "transparent" enough to not muddy up synths. Very nice to be able to roll off lows. All in all a very nice reverb. Though I will admit, that for the price I sometimes feel that I'm not getting enough useable reverbs for synth work. Don't get me wrong, it's awesome (ESP for guitar), but about half the options just aren't ideal for synths (room too muddy, spring doesn't pair well with synths, shimmer a bit too delayed for anything but pads, modulation is gorgeous but a tad subtle for non-percussive sounds).
Helix:
I got this pedal because it was cheap ($65 used), has stereo ins and outs, and with the tone prints seemed to have great flexibility. However, I'm not super into the sound. Can't quite explain it... there's nothing wrong with it, but I've yet to have a moment of feeling anything magical comes out of it. It lacks warmth and bass, immediately tends to thin everything out, feedback isn't very musical... overall I just have the sense that the phasing effect never really "becomes part" of the sound, but rather sort of transplants it with a lesser phased copy. Not pleasant and will probably replace someday soon. Hoping Strymon will build a phaser soon!!!
