The Pearl Masters series is indeed a favorite among drummers, and it offers several options tailored to different sounds and preferences. The two main types within the Masters series are typically the Maple Complete (MCT) and Birch Complete (BCT). Maple kits are known for their full-bodied, warm tones, making them versatile for both live performance and studio recording. This would suit you well for rock due to its punchy sound, but they also handle jazz nicely because of their dynamic range.
Birch kits, on the other hand, provide a brighter, more focused sound with pronounced high frequencies and a solid low end. These qualities make them great for articulation and projection, which can cut through in a live setting.
For someone who primarily plays rock but dabbles in jazz, the Maple Complete might be the best choice. It gives you that warm, resonant sound you need for rock but can also be nuanced enough for jazz.
Regarding deals, consider checking out both online music gear retailers and local drum shops. Online, look for sales events, open-box deals, or discounts on previous year's models. Local shops can also offer competitive pricing, and you might get a chance to test the kits in person, which is invaluable.
Keep an eye on forums and groups dedicated to drum gear; sometimes, other drummers will sell lightly used sets at great prices. Just remember to evaluate the condition if buying second-hand. Good luck!
