"Medium bore" Bb-F tenor trombone is a new idea to the industry. By adjusting the bore size into 12.90 mm (0.508"), players have more flexibility on this trombone and will feel easier to play. This new trombone is not also definitely good for Bb-F tenor trombone starters who are still not familiar enough for normal large bore Bb-F trombone, but it also good for professional trombonist players who play in small group or prefer smaller core sound.
We design the new "light weight" bell for this new trombone model, which is easier to create the sound with a bit brighter (more resonant) sound. In additional to the light weight bell, full nickel silver hand slide help players to find the high octave easily.
