Currently I don't use a pick, but I'm getting interested in adding that option ... I never played guitar with a pick either so total newbie, I have no clue on thickness, size, etc. I realize it's down to personal preference once you get into it, but is there something considered a bog standard pick I should buy just to get started?
Yes it's just personal preference, and picks are cheap, so there's no reason not to buy three or four different ones and try them out. Brand doesn't matter too much. Probably "standard" would be any brand in a teardrop shape and either medium thickness (which is like .7-.8 mm) or heavy (about 1.0 mm). I like heavy myself on bass strings. There are little "jazz" picks but I find them too small for bass, and then the big triangular ones which are OK. But just get some and try them out.
Yes, it's not a major investment so I guess I'll go down to the local shop and grab a couple. I'll donate the ones I don't like to the guitar player.
As a baseline, you can't go too wrong with the Dunlop Tortex picks - they seem to get a lot of love, and are color coded by thickness. For bass, I'd get a pack of yellows, greens, and blues and start with those three and see what you like from there.
I'd say get a bunch of Dunlops, an assortment of nylons (black and gray), 500s (pink and magenta) and Tortex (green, powder blue, and orange. For bass I like the black, magenta, and greens the best. Also try using the two bigger rounded edges for a mellower sound.
My proud little test collection I had a go at Flight of the bumblebee but quickly lowered my ambition to Twinkle twinkle little star, which didn't work either. This will take some time ... What's with the turtles and alligators?
Fender Heavy 1.0 was a standard forever until Tortex came along. Still worth a try. I like the Dunlop Jazz III carbon fibers. They may feel a little small and hard to handle if you're just starting out, though. Different picks have different sounds. Try a bunch.
Not sure about the alligators, but I think I heard that the turtles are there because they used to make them out of tortoise shells.
A .88 Tortex (green) is my go-to for pickstyle... granted, that accounts for maybe 10% of what I play.
