Used by many top studio players.
Kanstul's largest trombone, the Model 1690 F contrabass 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 it used by many in the studios of Los Angeles.
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.
Artists currently using the 1690 include top studio players Phil Teele, George Thatcher, Bruce Otto, Craig Gosnell, and Bob Sanders; Jeff Cortazzo of the U.S. Army Blues and Capitol Bones, Joe Barati (Harry Connick, Jr.) and Paul Pollard of the Metropolitan Opera.
The 1690 trombone features a dual bore .562"/.608" nickel slide with extended water key. 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.
