I would without a doubt recommend this to any acoustic or bass player (as myslef).

I like this pick because it doesn't give a harsh sound of a pick and gives a warmer, finger-pick like sound. My only negative comment is that being made of rubber, it takes a little getting used to playing with one of these because there's more friction between the pick a strings.

Any bassist knows that there's a certain tone and feel you can only get from your thumb, but being limited to just a thumb sucks. Your thumb limits you, even with backstroke techniques because it still changes tone.

When you use one of these (which ever size/type you prefer) you retain the sound qualities of a thumb, but gain the playability of a pick, exactly what every decent bassist needs.

That, in my opinion, is a five-star pick.

You get a pack of three too, I thought I was only gonna get one.

Get some, you wont regret it.

Bought them, 3.1 and 5 hard, for bass and yes, they're way better than nylon picks but still doesn't sound like playing with your fingers - def a pick sound. Still nice. And they're great for electric leads (less noise and allows the notes to come through thicker) and acoustic rhythm, and mellow arpeggios on both. Despite what some have said, I haven't had much problem with "boogers". The picks are quite durable - may not last until you finally lose them (nylons), but aren't dead in a matter of hours, either. Also, they're easy to adjust to - if anyone says otherwise it's user error. I have no problem doing arpeggios on an elec with a 5mm. Lastly, come in sets of 3 (not noted in the description), so the value's actually pretty good/not as expensive as they seem. Def a unique sound - punchier than fingers but more mellow than nylon.

I use these for picking my ukulele. They work great on the nylon strings. Good grip and maintains that nice mellow uke sound. Doesn't soften up like felt pick.

Despite some customer comments about shredding and "eraser boogers" I decided to try a couple of these picks. I LOVE them and have not experienced any problems, and am well able to strum with them. They work pretty well for bass, although I prefer finger-style for that. I don't use them on acoustic, and they (esp. 5mm) may be clumsy for that with close steel strings. But what I REALLY love them for is when I wish to use a pick with my classical guitar, but don't want to use anything too harsh on nylon strings. These picks are PERFECT for that, and the 3.1mm works with classical string spacing for either strumming or picking of individual strings, even cross-picking. Try it, you'll like it!
