We're honoured to introduce you to another one of our endorsers, and what an endorser! 🎻🎢

Thomas Martin doesn't need to be presented -he's a living legend of the double bass, whose contribution to the double bass world as a soloist, orchestral player, researcher, editor, luthier and educator is invaluable.
Thomas has been happily using our rosins since last year, and has been a great supporter of our products!

We are honoured to share a review of our products by the wonderful violist, composer and innovator Oene van Geel, one of the most creative and interesting musicians we've ever had the luck to meet! 🎻🎢



"How wonderful that Severiano Paoli makes his own special rosin. Being a string player himself he knows what grip is needed to pull out the sound. I enjoy his violin and viola rosin!"

Are you a teacher teaching young bassists? Are you a younger player with a fractional instrument? This is for you! 🎻🎢

At 050Rosin we produce three bass blends: Hard, Soft and Super Sticky.

When playing on fractional basses (1/2, 1/4 etc.) we recommend our Hard blend. Fractional basses and strings do not require as much grip and stickiness as their larger counterparts, which makes our Hard rosin ideal for it: it will give your bass the rich, noble tone you expect from 050Rosin without any grit or excessive stickiness.
Also, it's a lot safer in terms of possible melting disasters when put in the hand of a younger player πŸ˜…

No matter what size, shape and type of bass you play, 050Rosin has got you covered!

Two cello rosins from the same batch, yet they look different! What's going on here? πŸ•΅οΈβ€β™‚οΈ

These are two cello rosins, from the same run. One came out rather smooth looking, whereas the other one has some superficial hairline cracks. Is one of the two rosins spoiled?

NO! πŸ“›

All of our rosins are made of natural ingredients, and are handmade. Some of the ingredients we use, especially in the cello rosin, are by nature susceptible to changes in temperature and humidity, both while pouring them and afterwards; this can lead to small imperfections like the one in the picture. Yet, such imperfections are only cosmetic, and they have no impact whatsoever on the sound, usability and overall quality of the rosin.
While we do our best to maintain our production as consistent as possible, little imperfections are unavoidable.
We also avoid over-polishing our rosins -we could add ingredients that would make it easier to make them look good, but that would mean taking away from their sound quality and playability, and we're not going to sacrifice those for a purely aesthetic matter.

And we would find it a pity and a waste to throw away a perfectly functioning rosin because of a small aesthetic imperfection! Waste of resources is something we strongly strive against, and we try to give our little contribution to reducing it as much as possible.

So, if you see little, shallow surface cracks on your rosin, there is nothing to worry about! And those will make your rosin unique! 😊🎻🎢

NOTE: if your rosin shows deeper cracks, is cracked throughout (unfortunately, courier transport can be rough at times), or any other issue, please do not hesitate to contact your retailer and/or us directly, and we will do our best to assist you!
