Characteristics, I think we went around.

UTILIZATION

Use, ditto.

SOUND QUALITY

This little box I have a big problem. Let me explain:
I was looking for a boost out of the mix on my solos. I already have the RC booster of the same brand but it improves my clean sound so I can not use boost.
So I acquired The EP booster and boost issue, it's perfect, it adds all Db needed.
But then I noticed that it adds a great addition to the OD sounds when you put before the EP!
So, here I am very annoyed because I wanted to use the boost pedal!

OVERALL OPINION

This is a recent purchase but I already knew about the PB another scratch. I would be an edit later according to my impressions. But there is not to be mistaken, it's very good.
I know a lot of boost and price / quality ratio I think this one is unbeatable.
Nine 115 EUR with shipping, I have not really complain.
I would do this choice with your eyes closed and as stated in an earlier opinion, it would take two, one before and one distortion in boost!
Besides, I'd think seriously about this event but I have a preamp pedal + boost happens. I hope I do not regret it!
