Boss pedal (I recommend) to delay, so a good echo. Pedal with an analog input jack (6.35 mm jack in all), output jack, another output which I still have not found the true usefulness. Connected with "live out", the pedal does not work.
The location of the battery is located under the hatch and there is also a jack for a 9V adapter (use only the adapter boss).

UTILIZATION

Configuring more than simple: three knobs but be careful if they are pushed to the maximum all means a high-pitched noise and I suggest you all down quickly to avoid damaging your ears.
It is the first "repeat rate" which, as its name implies, determines the number of repetition of the echo
- Then the button "echo" that rule is not much more or less power
- The intensity adjusts the intensity!
My advice: an echo and maximum intensity and minimum repeat rate
I put 5 as the repeat rate is only used to make a shrill sound to more than 3.5.

SOUND QUALITY

The sound quality is excellent. that's all I have to say

OVERALL OPINION

it's about 6 months I use it, I got it with a marshall amp that someone sold me 5275 (€ 150 the lot !!!!)
I find it excellent and I recommend it.
