The Grover Pro 10" Studio Pro German Silver/Phosphor Bronze Tambourine gives session players the professional-quality sounds of the original model, without the added timbre of the head - a modification LA and Nashville players had been doing on their own with a knife for years!
German Silver jingles are bright, clean, and typical for a go-to sound while Phosphor Bronze is much mellower and darker in tone. The combination of these two jingles provides you with a mixed sound that lies somewhere in the middle.
Dual-width staggered jingle slots force different jingles to strike the shell at different times when you perform a shake roll, effectively 'rounding out' the sound to make it smoother and less rhythmic.
A soft rubber ring around the top edge of the shell makes playing with your hands a little bit comfortable, and playing with your sticks less dangerous for the instrument itself.
