When I need or want to use a multi-effects unit, in a really small board set-up, it'd likely be one of these two; but I tend to prefer dedicated pedals, combined with an Walrus ACS-1 on the tail end (If I'm going amp-less, which is usually the case, since a lot of my playing is in the middle of then night, and through headphones, in this little apartment LOL).
I may eventually sell at least one of these two (probably the HX Stomp, since I like the GT-1000 Core's interface better - and also probably since I've been using BOSS products, on and off, for forty-plus years (to include their GX-700, GT-3, and GT-10 multi-effects, which started in 1997).
The jury's still out on that. I feel like I'd take a big hit, trying to sell either of these, and since I'm not in dire straights, financially, I'm not really wiling to do that.
A few years back, I had this hair-brained idea that I was going to create mini boards, based around these two -to use in smaller venues, or places where it would be uncomfortable or ill-advised to bring in a big, expensive, heavy board - but it never really materialized. I'm still not really gigging again, any more. That could change, but so far....
I'd probably have been better off just buying three or four nice, dedicated effects, instead of those two.
