Electro-Harmonix offer tremendous value for money with this pedal as it includes various delays, shimmer and sampling - plus a looper is also built-in. With a power supply included it offers ridiculously good features for such a sensible price point.Although containing all of the above, it still remains extremely compact and pedalboard-friendly. The delay types range from digital, modulated, multi-tap, reverse, Deluxe Memory Man, tape, reverb with delay, octave delay, shimmer, sample and hold and a looper that has 62 seconds of maximum recording time available. There is tap-tempo built-in meaning you can get the delays in-time with your music easily. The delay times vary from 5ms to 3 seconds, giving a huge range of delay styles. There are loads of options built-in that can be accessed via secondary dial functions. Echos can trail or be cut-off immediately when bypassed. An awesome little pedal.
