Yes, all the CX, MX, and LX drums were maple, made in Mexico. The FX series was birch and also had a matte finish, and were made in China. The 2nd gen had the same mounts as the others; the 1st gen had Pearl- or Yamaha-style L-arm mounts.
Copied from my comment on an older thread earlier this year: "My Pacific CX kit still with the stock heads from '03 sounds ridiculously better than they should; they'd still be my gig kit still if it wasn't for my falling into a kit with more trustworthy hardware for me to schlep around (not that I've ever had a hardware issue with the Pacifics)." For years, I've only played them at rehearsals, and while between bands, they've gone stretches of time unplayed- I *refuse* to change the heads while they're still sounding so good! Fellow knowledgeable drummers as well as bandmates who didn't know drums from their butts have commented on how good they sound. I think those stock Pacific/DW heads are better than other kits' stock heads, but I'd hesitate to say they're better than Remo, Evans, et al; I think I just got lucky with these. I attribute the credit to this kit's sound to the shells.
