Some of the differences between the Session SRX and the Masters MMX or MRX (maple):
Masters uses stainless steel tension rods (not plated); Masterworks-type rubber gaskets under the lugs; the wood is top "A" quality; hardware is also available in black chrome, satin chrome, and gold; more color options; MasterCast die cast hoops on all drums; recessed bass drum claws with scratch-proof rubber gaskets that preserve the bass drum hoops; available in 4-ply 5mm 100% maple (MMX) or 6-ply 7.5mm maple (MRX); Masters drums also available in Birch and Mahogany.
Session: shares many features of the Masters; 6-ply maple; Masterworks style rubber gaskets, SuperHoop II rims; low mass lugs; etc.
Pearl's site lists all the specifics:
www.pearldrum.com. By the way, I found a surprising number of people who use the Pearl Masters BRX birch kits and they aren't that much more than the Session series....only a few $$....and they say they're great for playing live as they reallly cut through. There is a really cool Flash program on Pearl's site that allows you to build a kit using any size drums you want and then playing them on a timeline. You can then change the shells to maple, birch, or mahogany without having to rebuild the kit. This allows you to hear what the kit sounds like. I used my AKG headphones to get a better idea of the differences, but a good computer speaker system should do the job well.
Pearl's kits are most definitely a great deal. IMO they are, dollar for dollar, the BEST deal out there and some of the best sounding drums. I have played on Tama, but I prefer Pearl. However,
I believe you'd be happy either way. Just play them, check out the hardware and color options, and then compare price.
You might run into one or two people who have a
distaste for Pearl drums, perhaps for no other reason than blind loyalty to some other brand. I suggest you just look at both drum brands (or others) objectively when making your decision. Good luck.
