Great grip, takes getting used to

The matte finish really helps when your hands get sweaty during long sessions. It took me a few days to adjust to the smaller Jazz III size, but now I love it.

Perfect for heavy rhythm playing

These picks are exactly what I needed for downpicking fast riffs. The Ultex material is durable and the sharp tip gives great precision on individual strings.

Consistent tone every time

I use these exclusively in the studio now. They don't wear down quickly like nylon picks, so the tone remains consistent throughout multiple recording takes.

Best pick for lead work

Even though these are associated with metal, the clarity they provide for jazz fusion lines is incredible. The attack is very defined without being too harsh.

Dream Theater quality

If you want that crisp, articulate sound heard on Dream Theater albums, these are the picks to get. The 1.38mm thickness provides excellent control.

Too small for my hands

I bought these because of the Petrucci signature, but I found them a bit too small to hold comfortably. Great quality though, just not the right fit for me personally.
