Refine your Shires bass trombone's response with a leadpipe matched to your handslide. Venturi size, material, and length influence the balance of openness, articulation, and tonal character.

Bore and mouthpiece compatibility:

• B: For .562-inch-bore bass trombone handslides and large-shank mouthpieces.
• BB: For .578-inch-bore handslides and large-shank mouthpieces; a separate bore designation.
• For dual-bore handslides, match the leadpipe to the smaller bore of the upper tube. A .562/.578-inch slide therefore uses the .562-inch leadpipe specification.

Venturi:

The central number identifies the relative size of the venturi.

• 1: Small venturi; centered sound with clear articulation.
• 1.5: Medium-small venturi; combines small- and medium-venturi characteristics.
• 2: Medium venturi; open sound.
• 2.5: Medium-large venturi; more open sound.
• 3: Largest venturi; large, broad sound.

Material:

• Unmarked, yellow brass: Balances warmth and brilliance with a clear, articulate response.
• N, nickel silver: Brilliant and clear, with crisp articulation and response; may limit tonal flexibility.
• G, gold brass: Warm, dense sound with rounded articulation; may reduce clarity.
• SS, sterling silver: Strong fundamental and presence, with clear attacks and a simpler overtone character; may offer less warmth and brilliance.

Length:

• Unmarked, standard: 8.75 inches for brass and nickel silver; 9.75 inches for sterling silver.
• L, long: 9.75 inches, favoring a more centered sound and feel. Sterling-silver pipes are already this length as standard and have no separate long version.
• S, short: 8 inches for brass and nickel silver; 8.75 inches for sterling silver. Favors a more open sound and feel.
