A wonderful collection of effects built in with the ability to add more effects with Zoom's iOS webstore. Sadly Zoom has stopped releasing new effects but there are a ton to buy. The AMP sims are a bit meh but where the pedal really shines is it's massive collection of delays.
Wherever I take my guitar, I've this great multistomp with me. Due to its small dimensions, a single stomp size, you can put it inside your gig bag, as a Swiss knife that you have always with you at rehearsals, or at any improvised jam. And, moreover, as backup pedalboard in your gigs. And it's great it works with just 2 AA batteries, so you don't need to carry any power adapter.
