Very nice concept. Not really a fan of the sliders though.
Probably just stick with the Illumine. Kicked Strymon to the curb for me.
I don't really have any issues with sliders on pedals.
The very few that I have with sliders (Walrus Sloer, BOSS EQ-200) still seem to be going strong, without any dirt build-up, noise, or dependability issues (so far, at least); so I guess I've been fortunate. But I'm fanatical about keeping my pedals clean (have too many thousands invested in them, not to), and I've been using make-up brushes (of all things) to remove debris from the pedals, before it ever has a chance to wreak havoc on them (and it's a lot quicker, using the brushes, rather than very lightly-dampened cloths, trying to squeeze in between some of the extremely close-together knobs, buttons, and toggle switches. It used to take too damned long, that way. Now, a pedal is good to go in just a few moments :-).
I was intrigued by the Illumine, when it was released, but kind of passed on it, since I don't think I could really take advantage of it's many capabilities without a MIDI switcher. That, and I already have a bunch of nice reverbs (even more delays), since they're my favorite effect (especially nice delays).
Hard to justify the expense.
They sure do sound amazing, though (from the demos I've seen and heard of them).
How long have you had your Illumine?
Years ago, the Immerse Mk II was on my radar for a while, but I never got around to picking one up.
I don't own any Strymon
reverbs, other than their Cloudburst, which sounds glorious.
If I ever use the Ensemble feature (which seems to be rarely), it's dialed way back and with the tone turned way down. It's too easy to overwhelm the music with that feature (in my opinion).
Maybe the experience would be different with humbuckers (?).
