The PQP-0500-TD is 6 pcs. pack of TUSQ Teardrop shaped picks. They come in various gauges: 0.88mm, 1.00mm, and 1.40mm thickness. They also come in various tones: Bright (white color), Warm (vintage cream color), and Deep (gray color). The type of pick you use affects the tone you create. That's why we created TUSQ picks, the world's first and only pick with a built-in tone. By formulating various composite materials, we created a new class of picks with highly resonant characteristics that produce three distinctive tones: Bright, Warm, and Deep. TUSQ picks have a high stiffness-to-thickness ratio, like real tortoise shells but with a harmonic content, only TUSQ can deliver. Experience a smooth, balanced feel and a clean articulate attack. With TUSQ in your pick, a great tone is in your hands. Now you can choose your gauge, your shape, and now your tone.
