Get ready for the guttural tones of LP's new Jam Block/Guiro. Crafted of LP's patented Jenigor formulation, it will deliver the rich low tones of treasured (and fragile!) old wood blocks with an added component: A dual playing surface, one with traditional surface, the other ridged in a series of grooves. The latter enables glissando and guiro-like effects. Again, the LP Jam Block/Guiro is strong, incredibly durable and capable of great projection. A heavy duty mounting bracket and an LP eye-bolt assembly are included.
