See fact sheet on the site! But I need not think drawing is written large on the pedal!

UTILIZATION

So it's easy! You plug it turns knob and voila!

It is this branch loop in the loop of the amp or the beginning of the chain.
In my case I put the end of the string and it works very well!

SOUND QUALITY

While efficiency side nothing to say it does what is expected of her and she does really well.

OVERALL OPINION

I recommend to all! Well I have system tries this one but there are other competitors that you it Boss or Rocktron but I did not ACCase them to try them so I would not say PSI is not the best, but I agree she perfectly!
