I can honestly say that for me, the sunrise 1.5mm is the perfect guitar pick. The tone is incredible, the grip is fantastic, and even though it seems expensive at first, as long as you keep up with it, you’re getting your money’s worth. I’ve been using the same pick for about a year now, I believe. I think the only downside is that it doesn’t indefinitely retain its edge. Some players like how a pick forms to their playing, but I personally don’t. I enjoy the snap, punch, and immediacy of a freshly cut Gravity pick. This is a sad truth for all guitar picks though, they wear down. (Maybe Gravity could offer a re-beveling service?) Considering that I probably would’ve spent $20-$40 in Jazz III’s a couple years ago, and surely would have lost each and every one of them by now, I consider this Gravity pick to be money well spent.
