Ultra Formulation Supreme Bass Rosin Soft
Top customer reviews
While Pop's is great and one of the standard rosin brands for Double Bassists, I have always preferred Kolstein's brand (and not because I owned a bass and bow from the luthier Sam Kolstein for years- comparatively, it just surpasses Pop's performance). Pop's is just too soft and with Kolstein it is just the right consistency to give you a good grip without being too sticky, runny etc especially in warm weather. It also does not get too hard or have a tendency to crack in colder weather as Pop's does. You can tell by the sound when someone has too much rosin on their bow and with Kolstein, even if you use a little more than you need it won't "glob" up on your bow hair and create that kind of "gravely" sound behind the note when there's too much. It gives you an excellent grip but still allows the bow hair to have a natural feel and sound on the string (also a little secret is that I always carry a toothbrush and brush off any excess rosin and separate the hairs). Pop's is so soft that with more inexperienced players, they can easily use far too much rosin and suffer from too much rosin build up on the bow hair which affects sound negatively.
You can see from the posted images that there is a much smaller quantity of the Kolstein brand than the Pop's. Why? Contrary to belief you really don't need much rosin at all if you have quality bow hair- (if you go with "AAA" level Moroccan horse hair in either salt and pepper or black, you really need very little rosin- if you use this same quality but in white, you just need a bit more on it than you'd use for the salt-pepper and black because the hair is naturally not as course. Ask your bow repairer/ luthier for this type of hair and you will hear a major difference in the bow sound before you even use any rosin. NEVER use synthetic bow hair. Synthetic hair combined with rosin equals bad tone.
Also the actual Kolstein rosin itself comes encapsulated inside a rubber sleeve (see images) that maintains the structure of the rosin itself within the outer gold cardboard casing and won't allow the rosin to stick to the sides in any weather. All I do is roll down the rubber just enough to draw the bow across it a couple times, let the rubber go and it keeps everything nicely in its place. This is an upgrade from back in the day when it was encased in a cardboard casing you had to peel off.
As you can see from the Pop's rosin (given to me to use from an instrument rental shop with a piece of the paper cup torn off ---huge mistake!). The rosin melts out of the cup often and once it gets out of its paper cup holder it sticks to the plastic cup. When it is not melting, it's generally cracking.
I suggest getting Kolstein's All-Weather grade (this is the ultra which works too) and you will be covered for well over a year by using sparingly on good bow hair. HAPPY PLAYING!!
I've tried and used a lot of various Rosin's over the years.
There are even some Rosins no longer made.
By every stretch, Kolstein rosin the absolutely the best rosin I've ever tried.
1: Unlike other rosins, over time the rosin doesn't "glaze", it remains consistent.
2: It has excellent aggressive gripping power on the strings. I love that.
3: It has excellent tone. You'd be surprised at the differences between rosins.
4: It does not take a long time to rosin up your bow. Other rosins you have to really warm them up
with many strokes. Kolstein rosin applies easily to the bow.
5: It doesn't create a lot of dust, good for allergic type issues and keeping the bass clean.
One thing to note, all Rosins are NOT compatible. Use up or clean off the rosin on bow before
changing over to Kolstein or any other rosin.
Kolstein Music has been probably the most reputable and expert bass dealer in the United States.
It's an incredible treat to visit their store and see their incredible array of vintage and new basses.
They have engineered a number of products over the years, various strings, cases, bridges, all with excellent quality
I also recommend the rosin to my students, sometimes giving them.
Picture of my 1930 Ferratti Italian Bass, Dolling German Bow, Kolstein protective Bib for a bass, and
an old cake of very used rosin. I got this bass from Barrie Kolstein as well.

I do have one issue with it, but it's about the container. The rosin is in a black silicone cylinder, and you have to remove one end (a cap) and then roll the edges down. It's really hard to get started. (My wife couldn't do it on her own.) Because it fits inside the golden cardboard tube even when it's rolled back, you can keep it that way, rest the silicone cap on top, slide it into the tube, and cap the tube for storage. I'm not removing a star for that, because it has nothing to do with the quality of the rosin itself—and rosin in general is notorious for being hard to contain.
