Item Details

After 38 years building the finest brass instruments, the Kanstul factory has closed.  The Kanstul family and team want to express their deep appreciation to our customers, business partners and friends for the business and incredible support they’ve received over the 38 years since Zig Kanstul founded the company.

June: We have one 1690SB trombone available.  It's already a collector's item.

This is the last of only three F contrabass trombones with a screw bell flare made by Kanstul Musical instruments in Anaheim, California.  These were finished in March 2019. 

The 1690 design by Zig Kanstul is loosely based on the Jurgen Voigt model 173 contrabass, and features proprietary Kanstul CR rotary valves in C/Db/A for easy scale patterns.  The fixed bell version of this horn has been sold worldwide, to Paul Pollard, Phil Teele, and many others in Hollywood and beyond.  The new screw bell design makes it easier to go across town or across the country.

From Kanstul's Website

Our largest trombone, the Model 1690 F contra bass met with immediate success when introduced, and is used in symphony orchestras around the world. Considered one of the top contra bass trombones in the world, we’re proud to see it used by many of our friends in the Los Angeles studios.

One of the difficulties of designing such a large trombone is ergonomics. The size and weight of such an instrument can become a burden for the player, and without proper ergonomic design simply exchanges musicality for stress. The ergonomic design of the Model 1690 properly fits the trombone to the human hand – distributing the weight in a sensible manner – and is adjustable. Large diameter ergonomic cork barrels and rounded connector nut, a neoprene covered hand pad, and adjustable trigger paddles allow a player to remain comfortable and focus on the business of music.

Though the vintage BBb contrabass trombone may be more famous, Zig Kanstul chose the key of F for his instrument to create a nimble voice that works with the player, rather than against him. As a solo, orchestral, or studio instrument, you’ll find that mastery of our F contra bass comes quickly, and any transpositions and longer hand slide positions are quickly learned. Any perceived advantages of a BBb contra bass are quelled after one blow on a Kanstul. For the experienced bass trombone player, the addition of the Kanstul contra bass will add extra opportunity for you to share your craft.

Some of our favorite players currently using the 1690 include top studio players Phil Teele, George Thatcher, Craig Gosnell, and Bob Sanders; also Jeff Cortazzo of the U.S. Army Blues and Capitol Bones, Joe Barati (Harry Connick, Jr.) and Paul Pollard of the Metropolitan Opera.

The Model 1690 can be heard on Mychael Danna’s Oscar-winning score for Life of Pi; and also on Sufjan Stevens’ “Planetarium” tour in 2013.

This trombone features a dual bore .562″/.608″ nickel slide with extended water key, and removable press-in mouthpipe. The inline CR rotors are stepped bore, in .630″ and .670″ to improve low range response. The bell is 10 1/4″ diameter yellow brass.
