Plectrum.
It picks the strings very nicely. It grips really well too, no turning and slipping.

Excellent
Very nice material. Great feel in my hand. Nice sharp point that holds it's shape after use and is slick on the strings so you can play fast easily. Best pick I own now.

Why haven't I used this 10 years ago
Literally the best pic for virtuoso playing I played the same pic like many others the Dunlop purple 3 mm but they always kept sliding off as I was playing faster because of the sweat in my fingers but this one is slightly thicker which feels ergonomically better but best of all what shines is the embedded grip design that you have to feel to understand you can literally hold this pic so light in your fingers with the added thickness and that grip from the pic design it will not fall out because we all know you cannot grip the pic hard during Yngwie Malmsteen runs or Michelangelo licks keeping the pick in your hand light and secure and the beveled point on the pic slides so nicely it was amazing playing for the first time I want to buy a thousand of these to keep LOL

Heavy Help
Hefty, encourages the player to strengthen both hands. Gives a fuller & stronger tone to notes and facilitates playing in the high frets..heavy pick plus heavy hands brings the high notes home!

Best for Big Hands!
I have big hands with fat fingers, and they get stiff doing yard chores to where nowadays I find holding a pick size 1.5 mm or thinner causes numbness in the fingers. The thickness of this pick is great as it eases the grip required to hold the pick, eliminating the numbness/fatigue I used to experience. Unfortunately, cannot play real well with anything thinner than these 4.20 mm, but that's ok because these make playing fun again.

Amazing for chunky metal riffs, not great for much else
These things are so ridiculous in the best way. When paired with thick strings, it gives a very full, chunky sound that is amazing for metal riffs. It sounds even better when I down-tune my guitar too. It’s definitely a specialized tool so there’s a lot that it’s really not ideal for, like any fast picking on the treble strings. But when used properly, it’s a great addition to any musician’s arsenal, and it’s tons of fun to use.

Thick as a brick? Yes. Still awesome? Yes!
I'd like to give a description for those who felt as I did before trying these. Prior to giving these a shot (out of curiousity) the thickest picks in my stable were 1.1mm D'addario black ice, and my favorite picks were the smaller 0.8mm from the same brand. My thinking was: how could a 4.2mm pick be good in any way? Well, it's all about the edge bevel they put on it. That bevel has the precision of a smaller pick, but it also provides a sort of energy to your picking hand such that it assists in "bouncing" to the next note. It's hard to describe - but it has a very different feel from what I anticipated. Pros: - material is very hard and feels durable. I have a LOT of picks that are worn down to an oblong circle shape, this is a lot harder - how they change your playing as described poorly above. This is the biggest delight and I encourage anyone to give them a shot based on this - texture provides adequate grip, no complaints - (listed as both a con and a pro depending on your perspective): sound with these is a bit brighter, with more clarity Cons / gripes: - they could have made this a triangle pick in a similar size pretty easily. - (listed as both a con and a pro depending on your perspective): sound with these is a bit brighter, with more clarity - It's a pretty expensive piece of plastic really

un de mes médiateurs préféré, j'aime beaucoup le son qu'il procure et sa maniabilité. Vive les médiateurs épais!

Great pick. Provides good grip in your hand meanwhile sliding well across the strings. Does not get stuck or bounce back. Provides good attack. I am a guitar player who bought this for my first bass which is a short scale. Now I am thinking of using this for my guitars as well. Definitely it will work awesomely on acoustic guitars. Would be great for chugging thrush metal as well

Jag som har nervskador och är svag i höger hand då jag ska greppa plektrum tycker detta plektrum är kanon. Är mer avslappnad i hand och handled då det är mer ergonomiskt och enkelt att greppa bra pga. Dess tjocklek.

Having played over 40 years, I've pretty much tried everything, including handmade custom picks. These are now my go to pick for acoustic and electric guitar. Here's why: 1. Rigidity: Many years ago I learned that rigid picks are the only way to go if you want to be able to pick fast and accurately. It's all about feedback: any flex reduces your connection. So for many years my minimum was 2mm, so clearly at 4.2mm, these fit the bill. 2. Fat picks reduce strain. A revelation to me was when I tried a custom 8.4mm pick: it was simply easier to hold. This is basic ergonomics, but was very counterintuitive. While I still have and use that monster, through experimentation I found that 4mm was the sweet spot between ease of grip and thinness to navigate string separation. 3. Microdot grip: the bane of many a guitarist is a pick slipping out of position between your finger and thumb. While custom picks address this with drill holes, the microdots on this pick seem dimensioned to interlock with the grooves of your fingerprint, resulting in a "lock" that is close to magnetic and the best I've ever encountered. 4. Ultex: so far, in my experience, this is the best composite produced for guitar yet. Hard-wearing, light, with a feel and tone comparable to real tortoiseshell, this material is simply the best I've tried. 5. Shape: the graduated point of this pick, inherited from the venerable Dunlop Jazz pick, gives the perfectly predictable and clean string release required for accurate and clear note articulation. In this case, the sculpting is perfect not only along the flat plane of the pick, but also across the cross-section, giving effortless sweeps and alternate picking. 6. Size: this is probably the most personal aspect. I prefer this size, but for those of you accustomed to the smaller Jazz pick size, this may be too big. 7. Price: having paid upto £30 for custom handmade picks, these are actually really good value for money and actually outperform those more expensive picks, largely due to the Ultex material and the microdots. 8. Aesthetics: who doesn't like a translucent forest green pick with "420" incribed in the middle? 😉 Overall, these picks work perfectly across nickel, steel and even nylon strings, giving a clear and beautiful tone. I've now built up a stock of 50+ of these and use them exclusively for all instruments other than bass or some some of my more narrow-coursed instruments (e.g. laud, where I use 2mm Ultex). They are that good.
