“What do you call these?”, someone once asked. “TRI-1”, I said.
Punning aside, the TRI-1 is my first shape, I was looking for a standard sized, but broader-shouldered plectrum, more triangular but not as pointy, and smooth corners and bevels all round. A rare beveled griphole, since a bevel reduces some of the functionality of the grip hole. This grip is still obviously there, but more subtle to the touch..
Kirinite is an amazing material, widely adopted by the plectrier community. And rightly so. Rich, colourful, good to work with, hard wearing, smooth finishing, and to top it all off, it makes your amp suddenly go to 11. It really does give you more volume, even if the tone quality reflects the material a little bit: it is quite a dense sound, compared with the airyness of Plexiglas® or the natural warmth of casein. But boy, can you play the heck out of these!
If your pick tin is like a toolbox, your Kirinite plectrum is the big wrench. Every toolbox needs at least one big wrench.
