It is here.

Finally from a top US brass instrument builder is a contrabass trombone that is worthy of its breed. Zig Kanstul in Los Angeles is now ready to release the world's best contrabass trombone.

Features include:

.562"/.593" dual; bore slide with removable leadpipe, bass trombone mouthpiece receiver, wide nickel tapered crook and nickel outer slide tubes.

Dual in-line CR rotary valves. Valves are pitched in C, Db, and A, eliminating the need for a slide extension handle. Acoustical elegance meets the contrabass trombone.

Patented Kanstul CR valves feature 4 piece hollow, skeletonized rotor mechanism, full .620" bore first valve, .655" bore second valve, fast action, pop-free venting, tight seals, no maintenance, and ergonomic comfort.

Perfect balance and playing comfort is achieved by the lightly braced bell section and a hand supporting pad that will fit against the back of the hand.

Proper bell positioning means long, but still familiar slide positions. Valve tuning promotes familiar scale patterns for a fast learning curve.

Look beyond pricey European contras and instead to this new Kanstul to produce the classic sound. Be the lowest, loudest, and proudest player around with this extra large trombone. Give new life and style to the sounds of opera, brass choir, orchestras, and to all of the music you love to play.

The horn also includes custom contrabass trombone mouthpiece, custom extra large trombone stand, and Glenn Cronkhite lightweight case.
