I've always been impressed with Yamaha's birch drums. I selected a Yamaha Stage Custom birch for a church where I was playing, and once I got that kit set up with new heads and a good tuning, it really sounded sweet.
I was SOOO on the fence when I got my bop kit a few months ago between the Stage Custom bop and the Gretsch Catalina Jazz bop kit. I went with the Gretsch because of the supposed sonic differences between birch, which is supposed to be a bit brighter, and mahogany, which is supposedly darker. Granted, the quality of wood in either kit isn't wasn't going to be top notch, but it is what it is. So far so good, I like the Gretsch well enough.
In any case, the drummer for the wedding band where I play trumpet uses a Stage Custom Birch kit - he has "better" drums, but he wanted a kit he wasn't afraid might get dinged up, and one he had no qualms about leaving on a truck. He upgraded the hoops with die cast hoops, and those drums always sound great with the way he plays them.
I'm curious to hear how you like these drums once you get them set up.
