I've almost bought the original Ditto Looper at least 3 times in the last month. And this comes out. I love the simplicity of the original Ditto, but I really like some of the features of the X2. I don't know what I'm going to do now.
I have the original ditto looper and it's excellent.
I used to have the 4 button Digitech Jamman Stereo pedal but I found it too complicated to use!! It actually spent most of it's time in its box because I couldn't be bothered to find out how to use all the functions (lazy i know!!) It was too much pedal for me!!
The original ditto looper pedal offers everything I want from a looper and nothing I don't want. Another advantage is that it's tiny so it takes up very little space on a pedal board. The new version is obviously a bit bigger so keep that in mind if space is a consideration?
