The type of pick you use affects how you play and the tone you create. That's why GraphTech created TUSQ picks, the world's first and only pick with 3 distinct levels of harmonics. By formulating their proprietary material, they have created a whole new class of pick that have highly resonant characteristics. The picks produce three distinctive tones: Bright, Warm and Deep. TUSQ picks have a feel and articulation like no other picks on the market, very reminiscent of vintage tortoise shell, crisp tone, and thin, yet stiff. TUSQ pick tones are all coded by color. White is Bright, when you want your tone clean, clear, precise and rich in harmonic content. The vintage colored picks Warm it up a bit, and TUSQ charcoal colored picks go Deep to give you a smooth, very warm feel and tone. You can view GraphTech's full range of brands and products HERE
