I use .38mm picks. Picks that thin require exactness in your playing. Not just hitting the string, but picking it with the same force as the previous and the next. There is no room for whimpy picking. It's going to depend on your style of music and how you play as to what thickness of pick you use. Personally, I don't feel any difference after 1mm. It's all the same to me. For you, it's going to be what you're comfortable with.

I'm sure there will be other posts expounding on the "qualities" of thickness. Material is also a consideration as different materials will develop a different sound when played.

I prefer to use 2.0mm Jim Dunlops, but I can't find them locally.

I got a 2mm dunlop reserved for the bass for when my fingers can't handle the picking.
I had a 3mm dunlop that I I kept in my mouth to help me concentrate. ;)
I tried both of the above on my guitar and decided they were too dark and cumbersome to hold. 0.8-1mm picks work great for guitar. Stiff to avoid bending, lightweight, altogether good for speeding. The thicker ones (2-3mm) had one advantage in use: their curved sides might help with speed. The sound wasn't worth it tough, as I'm not a speed picker anyway.

Ultra-light picks ala Xark really don't work for me unless all I want is to strum.

What I do use is a steel pick. Stiff, without the clicking noise of medium plastic picks (like the 2mm pick), mellower sound but not muddy (better than 2mm pick) without added thickness that might get in the way and it compensates for my light-handed playing (better than all plastic picks). But It's heavy, so it makes speed picking harder.



Between the 2mm dunlop and the 3mm dunlop I'd take the 3mm. The 2mm pick sounded "undecided" trying to balance between heavy and medium it ended up sounding weak to me. Between 1mm and 3mm it would depend on what I would be trying to play.

I have 2mm dunlop. .50mm fender, .70 fender and .70mm to 1.5mm marshall picks. I began with the .50mm to start using picks. I'm on 2mm now.

I use Dunlop Jazz 3 Black pick. I don't know the thickness of them though.

And I just realized how old this thread is...I'm sorry.

I like em big and thick. The mm don't matter to me as long as it's pretty firm. I can get used to a new pick in just a few minutes.

Thin picks for me usually fly out of my fingers and on to the floor. Also, thin picks slow me down when I'm ripping fast riffs and solo's. Maybe for acoustics and strumming I would prefer them... I don't know.

How about speed? I use, mostly, Dunlop .60 mm. They work good for me, but I still have a problem with picking. What's a good pick thickness and a good way to start improving picking? I just sound raggedy sometimes, and I don't like that. What can I do?

I think it's just a thing of personal taste. And really depending on the strings too. Why not use them...:)

I have in my collection a 3.0mm "Dadi - Passion" pick model, and it really gives an exceptional sound if you play slow blues, or some sweet melody, but it's bulky when you try to do anything else :)

I am a shred oriented and I think there is no better pick in the world than Dunlop Jazz III, small and sharp. On .10 strings, they're the best.
