What is better bass trombone with two or one trigger?

A bass Trombone with two triggers offers greater versatility, allowing the player to access a wider range of notes and harmonics, particularly in the lower register. The additional trigger facilitates smoother transitions between pitches and enhances overall performance flexibility. However, a single-trigger bass trombone can be sufficient for players who primarily focus on standard repertoire and prefer a simpler instrument. Ultimately, the choice depends on the player's style, repertoire, and personal preference.
