After about 7 years, I figured my 20" Clear EMAD had seen it's best days. Removed and installed an older, yet very slightly used clear Aquarian SuperKick II, which I had in storage, since I subsituted the EMAD for it, shortly after getting my kit. I play a 2009 Yamaha Maple Custom Absolute Nouveau. Surprisingly, the SKII sounds pretty good. As previously noted in this forum, I run a Carvin kick drum mic (a Shure SM52 knockoff) into a Sub N' Up octavizer, which then gets plugged into a small Behringer bass amp. (It can also go directly into my Behringer PA for gigs). I'm thinking of getting another EMAD or perhaps an EQ4 frosted bass batter, but for the time being, the SKII sounds pretty good mic'd up, and I also saved fifty bucks or so, which wifey likes. I guess now that it's properly mic'd, I don't notice much difference between the two. Anyone else have similar experiences with these two heads?
