This is true. Originally, I bought picks "designed for bass players"... NOT Good. Thick felt picks do not work for me. Then, I bought a variety pack, carbon fiber, nylon, tortex ranging in sizes from .88mm to 1mm or more. After some experimentation I'm favoring .88mm nylon because these are firm but flimsy enough to strum without getting stuck on a string. I also like the .88mm tortex. The tortex, like the nylon is .88mm. It is not as flimsy but it wears down. I've worn it down to almost a nub already.
As DavidEdenAria has stated, all picks do not respond or sound the same. The thicker ones are darker, the thinner ones are clanky. I'm using 40 - 95 gauge strings on my pbass (.88mm nylon pick), and 45 - 100 gauge strings on my jbass (.88mm tortex pick), and it doesn't work for me if I reverse picks to bass.
I will probably return to finger-style in the future whenever I tire of pick-style, but for now I'm really into using a pick totally unexpected, and I'm really digging it! Playing bass guitar for me is an experiment as well as an experience. I've always loved the instrument, as all of you do. I don't play in a band yet I have thousands of dollars tied up in equipment. I just love the sound of it, the look, the feel, everything about bass. I know you guys are just as passionate about bass as I am.
