James VanDemark
Professor Emeritus of Double Bass at the Eastman School of Music, James VanDemark has taught at Eastman for 50 years, and at the Round Top Festival in Texas for 40 years.
VanDemark says ” I was delighted to share the new Wiedoeft Bass Rosin this June with the terrific bass section at Round Top, and their enthusiasm was as great as mine. In both grades – All Season or Ultra Grip – Wiedoeft provides the player with an even, dependable, and powerful grip and responds to each individual player’s demands with ease. The quality and evenness of the rosin – not to mention Wiedoeft’s easy, no fuss packaging! – makes for an unbeatable combination for any player. ”
VanDemark has performed as soloist with many of the world’s major orchestras, including the New York Philharmonic, Minnesota Orchestra, Netherlands Radio Orchestra, National Symphony of Mexico, and many more. VanDemark is the recepient of works by four Pulitzer Prize winning composers. VanDemark’s students also perform in major orchestras and teach at major schools and conservatories throughout the world. Seven of VanDemark’s students have been Grammy nominated in a variety of musical genres, with two Grammy winners from the studio.

“As a jazz bassist, I use the bow far less than my classical counterparts, so anything that gives me an advantage is welcome. Wiedoeft Ultra Grip provides exactly that. The moment I put the bow on the string, it grabs perfectly—consistently, evenly, and smoothly.
There is no question that it has improved my sound. It is easily the best rosin I have ever used, and over the years I have tried more than I can count.
I am still experimenting with the All Season formula and getting excellent results. At this point, I can honestly say I am in rosin heaven.”
