Wiedoeft Rosin delivers a professional-grade, powerful, smooth response with excellent tonal quality for demanding musicians.

Manufactured in the USA from premium ingredients, Wiedoeft rosin is formulated for exceptional consistency and long-lasting performance on the bow — available for violin, viola, cello, and double bass.

Each cake comes in a durable roll-down silicone case that protects the rosin's shape and quality across climates, resists melting, and keeps things tidy when not in use. Wiedoeft rosin also boasts excellent shelf life — it resists drying out and crystallizing, so a cake stays reliable for the long haul.

Bass Rosins

All Season (Original Formula)

The classic Wiedoeft formula players have come to trust — smooth, warm, and just the right amount of sticky. It's engineered to be as faithful as possible to the original Wiedoeft recipe from the 1950s and '60s, updated with modern production for maximum consistency. A nice, moderate grip that isn't overwhelming — a few smooth strokes rosins the bow well, so a little goes a long way. Tonally, it offers clarity without harshness, and warmth and depth without becoming boomy.

Best for: players who want dependable, all-around performance across most conditions and want to avoid over-rosining.

Ultra-Grip — NEW

Wiedoeft's newest bass rosin formula, built for players who want maximum bite. Ultra-Grip is a stickier, more aggressive formula than the All Season rosin — closer to some of the softer, grippier formulas out there — giving you extra "sizzle" and power right off the bow. It's especially useful in colder climates where standard rosins can feel too slick, and it brings out extra warmth from the instrument. Comes in the same square, roll-down silicone case for easy, mess-free application.

Best for: players chasing more grip and projection, or performing in colder rooms and halls.
