I was sitting here thinking, "Lucky me, I never GAS for anything outside my little niche", and then this photo reminded me that I'm full of s***.

I have almost no use for clever clever semi-multi-FX pedals. (I'm almost always running a full-sized modeler/MFX unit, or a DAW, or both.) But pedals like this one always grab my attention. I've nearly purchased a Chroma Console countless times, but it's just expensive enough for me to keep my wits about me.
See also: modular synths even though I don't really play keys (and don't particularly like the sound of modular synths); control surfaces (Ableton Push, NI Launchpad, etc.) better-suited to DJs than guitarists; all the crap Teenage Engineering tries to sell me even though it costs a million dollars to go "bloop"; extra oddball stompboxes by the likes of
Alexander Pedals, willfully obtuse yet somehow irresistible...
All these toys
look infectiously fun - but I seldom (if ever) have a practical use for them.
