King Ergonomic
One of the thickest picks you can find online. If you're used to 1mm and below, it will feel strange playing with it. It is not for acoustic strumming, strictly for metal: fast shredding and power. A thin pick has more treble when played, and a thick pick has more bass when played. The thickness helps you hold the pick tightly and ergonomically in your hands. The inscription on the pick initially made me uncomfortable to hold, but at the same time, it makes the grip firm. Sweaty hands can cause dirt to accumulate. Bottom line: Consider all the things I mentioned above before purchasing. Always check the price history. I got it for ₹875.

New favorite pick Long lasting, awesome feeling
This is my favorite pick now. Lasts more than any other pick i have. And feels comfortable to hold no matter the conditions. I highly recommend you give it a try if you like thick picks.

I named it Mr. Chungus
Overpriced but worth it. Pack of 3 or 4 at this price is valid. Materialwise it's an absolute unit but not bulletproof and will get nicked or chipped by the 1st string if you abuse it. Overall picking is extremely fast, note weight is heavy. the picking feel is cushioned and butter smooth which is weird but you'll get used to it.

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.
