The Ultimate Guitar Plectrum / Pick

My vote for the ultimate plectrum for alternate picking would be the 2mm Dunlop Jazz III in black Ultex.

The thing is stupidly fast with a great tone and no weird artifacts.

Is your pick this fast?

My choice for all around great pick would be the Wegen Big City. Great grip and tone with a nice, positive attack on the string with no bad artifacts.

Give them a spin.
