What is your opinion of this product?
The heads are a pro level upgrade for Any bass drum.The EQ pad adds additional muffling & is removable. The Kick Port is a sound enhancement option, live or recording,it acts like a speaker cone, place the mic in front of it. This kit is worth the price BUT the kickport Will Not fit the Evans cutout, it will have to be completely cut away and not reusable. I use the Evans head as is and installed the kickport on the head I removed.Be careful, a exacto knife is required for cutting the bass head, it is easier to install the kickport with the head removed, plan on spending an hour to install the complete kit.
