More volume and less pick noise.
The Gold Series is a premium material offered by Gravity Picks. The material is a high grade thermoplastic which is amazingly wear-resistant. There is a sizable difference in volume when compared with a normal pick, enabling you to cut through the mix.
I guess not many are going know about thicker picks. However, 5mm is not an uncommon thickness for gypsy jazz or metal players. And it should be more common for bluegrass flatpicking and jazz. Thicker picks are perfect to add presence and volume to an acoustic instrument. And this one, with it's unique material, has a very clear sound. Much prefer it to gypsy jazz picks made of softer material or some of the oddly shaped boutique picks for metal guitar. Overall, this isn't my first choice for an electric archtop where I want a bit more subdued tone. But it is very good and will be my primary for a flat top or gypsy jazz guitar. And it's quite comfortable to hold and play. Well made. One of those 'expensive but worth it' things. And, if I don't lose it, the material will last a lifetime. If I do lose it, I'll buy another.
I didn't want to like it (Stealth XL 1.5mm). I had tried other, even more expensive picks looking for that right mojo and was hoping that it wouldn't be too pricey when I found it. Well here it is, the magic I was looking for. Great feel, dynamics and that "smack" or "pop" sound with almost no pick noise (how is that even possible?). Perfect for everything from aggressive electric soloing to acoustic strumming. I've been loving the Acrylic Series but the Gold Series Stealth is where my mojo's at now.
I was really hoping that my magic picks would be a little more affordable but, if you want perfection, sometimes ya gotta loosen the purse strings a bit. I will be buying more.
