I bought this one for my son's cello. Before I bought this, I've used the Ovid system which is really great for the price you're paying. I've also used the DPA d:vote Core which is in the upper price range and choice of many professional musicians. Unfortunately, the price is beyond what I'm prepared to pay for. The Ovid was ok though I found the cable quite thin. Then I saw this Audix ADX 20 i-p. It looked promising. Priced a lot more than the Ovid system but a lot less than the DPA. Needless to say, I'm very satisfied with my purchase. Sounds fantastic and built like a tank! I can highly recommend this product. But should finances not allow you to buy this, get the Ovid System but just be extra careful with the thin cable.
