I bought a few of these for some loud sources I'm dealing with in my studio such as my subkick, LDC overheads, SDC's on close mic'd drums etc. The sources are very hot, so I needed some pads to not clip my mics in digital and this little thing caught my eye.
It's way cheaper than most of the competition and it's pretty versitile in offering you 3 steps of padding. Overall, great product!
