Ok, you have a dobro and a bar, what else do you need? Picks!
On dobro it is standard practice to use 2 metal fingerpicks and a plastic thumbpick, so that's a great place to start. The fingerpicks should be fairly easy to fit, but the thumbpick is finicky. Here's my take on the picks, and I'll include links to what I use!
Fingerpicks are pretty easy since they bend to the shape of your fingers.
I use propik, straight, single wrap, brass fingerpicks, one with a medium blade and one with a wide blade. Weird! I'll tell you why in the video, here are links to them at teh coolest store in the world, Elderly Instruments.
