TC Electronic Ditto X2 vs X4: Which Looper Actually Earns Its Space

By Mike · Published September 22, 2026

The original Ditto looper is one of the most quietly influential pedals of the last fifteen years: it proved a great-sounding, dead-simple looper didn't need a menu, and TC Electronic has spent the years since building bigger versions of that same idea without losing the plot. I've owned the X2 since 2017 and added the X4 a few years later, and they're not really competing products so much as two different answers to "how much looper do you actually need."

Why I own both of these, too

Same story as the two Kempers in this rig: the smaller unit didn't get replaced by the bigger one, it just got a more specific job. The X2 is what goes on a board that's already full and just needs a loop function bolted on. The X4 is what goes on a board being built around looping as a real part of the set, not an afterthought.

The X2 case for staying small

The X2 keeps the original Ditto's entire philosophy: small footprint, two footswitches, stereo in and out, unlimited overdubs, and nothing between you and recording a loop. There's no drum machine, no menu-diving, no learning curve worth mentioning. If your looping needs are "record a phrase, layer over it, stop, undo if I mess up," the X2 does that with zero pedalboard tax, which is exactly why it's stayed on boards that otherwise have nothing to do with looping as a main feature.

The X4 case for going bigger

The X4 is the version built for players who want looping to actually be part of the performance rather than a background utility. Two extra footswitches open up real-time control you don't have on the X2, on-board rhythm/metronome functionality for practicing or building a loop against a beat, and more flexible loop-stacking behavior for building up an arrangement live instead of just layering one long phrase. It's still a stompbox, not a full looping workstation, but it's clearly built for someone who plans to stand on it more than occasionally.

The real decision: footswitches and floor space

Strip away the feature list and the real question is the same one that governs the rest of your board: what do you actually need under your feet in the moment, and what are you willing to give up in space to get it? Two footswitches force simplicity, which is a feature, not just a limitation, when you're already managing a drive, a modulation pedal, and a tuner on the same board. Four footswitches buy you real-time control at the cost of real estate and a small learning curve. Neither is the "better" looper in the abstract; they're sized for different jobs, the same way a starter board and a gig board solve different problems.

Which one to buy

If looping is a texture you reach for occasionally, on a board where space is already tight, the X2 is the right amount of looper and nothing more. If looping is a real part of how you write or perform, and you're willing to dedicate real board space and a couple of footswitches to it, the X4 is worth the extra room. I kept both because I have boards built for both situations; most players only need to build one board, so let the gig, not the spec sheet, pick the pedal.
