depends on the Rosin. If you are using Pops, it will build up on the strings really quickly. Maybe a few swips on the first bow and no more than a couple on the rest.
With finer rosins, it'll be less of an issue.
As an aside, I use Carlsson exclusively for practice and my own bass enjoyment, but I bought a can of Pops for a thing I did with a Orchestra this holiday season. While, certainly less refined, I can get a louder sound with Pops. Plus, it's so tacky, I can usually still get a decent bowed sound when I go into panic mode.
Anyway, last night, for some reason, I was compelled to take a swipe or two of Pops instead of my Carlssons before I started my exercises. IT SOUNDED AWFUL by comparison. It was so harsh sounding. The bow on the string sounded like an electric motor.
I hope I can get to the point where I never have to perform with it again. I'm really close. it had been a few weeks since I had used Pops and not only was the sound cheesy, but I don't like the bow feel as well either. I think Carlssons is the way for me.
