Punk/HardRock/StonerRock guitarist looking for bassist to jam

That's pretty much it. I'm a guitarist in Berlin in my early 30s. I'm working on a couple of tunes, riffs and such and would like to see if we have any bassists (m/w/d) out there who want to throw around some original heavy riffs with me. I'm not for labeling music but the ballpark is anywhere between punk, stoner rock and hard rock, maybe even a little post punk in there. I tend to tune down, I write predominantly in C standard, so I'm looking for anyone who likes to downtune as well.

I do best in english for communicating but would probably be able to express myself to some degree in german.
