Built with two autonomous loop channels which can operate independently or in tandem, loop decay control, and seven onboard loop effects including tape stop, reverse, and double, the TC Electronic Ditto X4 is one of the more powerful loopers available on the market. Similar in approach to the standard Ditto, this expanded iteration sports up to five minutes of total looping time for each loop to be chopped, cut, delayed, decayed, and more, all through the interface. Excellent for the experimental solo performer interested in adding more nuance to their performance. the X4 is also a solid option for anyone looking to dive in headfirst to the world of looping.
