Guitar World Verdict

A great resource for creating complex ambient textures that can also supply conventional delay and reverb when you are feeling less experimental.


  • +

    Delay and reverb in one pedal.

  • +

    Nice range of modulation treatments.

  • +

    Tap tempo.

  • +

    Easily implemented expression pedal control.


  • -

    Presets would have been cool.

  • -

    As would stereo operation, but for the price that's okay.

In its first foray into fully digital pedals, KMA Machines has put delay and reverb together into one stompbox. Nothing new about that, you might say – there are quite a lot of them around these days. 

This unit, however, is no standard two-for-one pedal. Described as a “spatial-temporal modifier”, it is quite specifically designed with the intent of using both effects together, complete with a set of modifying features, to create a bigger soundscape.
