Silence is a great bonus. This is a rducteur noise without encoding. Trs it works well on a guitar amp. The principle: The less level, the more it cuts the frquences less high. If the ear nicely, without too much to ask, it is absolutely transparent and substantially amliore source. I recommend it.
