This is a seriously good quality reso skin for your 24" drum. Don't be turned off by the price, because you'll never need to change the skin ever again (that goes for all reso skins IMHO). So do yourself a favor and invest in one of these. I previously played with a closed reso skin or without a skin, and then i turned to this and was blown away. It gives the perfect balance between resonance, pitch, and punch. Plus it allows me to get my bass drum mic just where i want it through the port hole. The port hole itself is also really nicely padded so you don't get those awkward squeaks or cuts when moving your boom in and out of the drum. In addition, it helps it from ripping and breaking, so it's another longevity boost worth paying for!
