Okay for the price.

I bought this,as most will, wanting a tube screamer pedal for cheap.

The plastic shell feels sturdy enough, but if you are going to be using it alot, id advise using a PSU as getting to the battery is fiddly and the hinges will probably break with time.

The tone pot feels low quality when turning, very loose and a bit scratchy, however I can live with that.

Recently I have been using this in front of a Orange Micro terror head, and it really does come to life when used as a boost to the overdrive, really thickening up the higher gain register.

When I bought this it was £18, and if you can get one at that price, do it. However, I would probably recommend looking into the Harley Benton TS clone since they are now the same price.
