Hand-made in Austria, Petz Premium Double Bass Rosin consists of pure resin and has excellent adhesion. It's on the softer side, but I don't find it to be "goopy" like some other soft rosins. Made in Austria.
kaftvoll und präzise! ("Powerful and Precise!")
Rosin is key in getting a good bowed sound, so don't cheap out on this key ingredient to success, it can last a long time - and isn't very expensive. In fact, some bassists carry two or three different cakes just in case the environment makes another consistency better for that particular situation. When the humidity is high, the more powdery, harder rosin is usually best, and during very dry periods some stickier stuff may be needed.
New players: I include my personal tip sheet covering the care and usage of rosin.
