My guitar teacher achieves extreme speed and control with this pick and extra light strings. I have yet to attain such speed, but the 3mm Stubby has yielded superlative tone, precision and control. The hard smooth surface of the pick glides over the string. The slick way the string leaves contact with the pick makes a mellow tone, you hear just the string, not the pick. The stubby was strange to me at first, but since my technique was getting a makeover, I adopted the new pick. I won't be turning back.
ConsToo few stores carry 3mm style. The associated technique is not for everyone.
