When I bought my second hand kit it came with Evens EQ3 fitted on the kick drum and had a massive sound even though the drum head looked pretty battered from the previous owner. At least the guys i sometimes play with kept saying that they feel my kicks in their chests (in a small room and no amplification on the drums). Then i noticed a rip in the outer ply underneath the patch where the beater hits and so it was time for a new one. For the reason to get one that lasts me as long as possible i went for the Evans EMAD Heavyweight risking some loss of sound in exchange of punch.
After fitting the the new head the tuning was easy. I went for the lowest possible pitch without wrinkles as it suits most of the music i like playing (Rock) and used the tinner of the two dampening rings it comes with. The punch now is massive again and the attack is huge. Where the old one had a big "Plop"-sound to it with the new one it sounds as if a "F" has been added to make it "PFlop". It sounds just great. I only practise with headphones on for ear protection and thus its more the feel in my body than an actual tone. Sure it wouldn't suit for Jazz and softer styles but if Rock is the main music played then it is a good choice. Now i just have to find out how long it will last me because that was my main concern to get the Heavyweight in the first place.
It arrived in perfect condition and including a single EQ protection patch, which should be added in the product discription as i bought this seperately and now with a single pedal is a leftover. So for double pedal players an additional patch needs to be bought if not a double patch.
All in all a great product and the dampening system works just perfect, in my case with some muffling inside the kick drum with access through a hole in the reso-head for more fine tuning.
