Bassist looking for people to jam with

I’m a bassist in my thirties who’s played in a bunch of bands in my teens and early 20’s but not too much the past few years. I’d love to find some people to jam with, write some songs and play the occasional gig around Berlin for the fun of it. Style-wise, when I was younger I was crazy about the Chili Peppers but now I’m more keen just to play basslines that groove: I’d love to play anything that’s groovy, a bit funky - a little RnB even. I'm really loving artists like Vulfpeck and Scary Pockets at the moment. Ideally, I’d like to jam 2 - 3 times a month and play a gig every month or second month but open to other arrangements.
