The Popular Large Rim – Bach 1 1/4 Style. .673" / 17.09mm inner rim diameter. This timeless rim diameter remains a favorite among advanced trumpeters who crave extra comfort, freedom, and tonal authority without sacrificing control. Modeled after the classic Bach 1 1/4, it provides a slightly more spacious feel than smaller rims, allowing for effortless airflow, reduced fatigue, and a broader, more resonant sound — ideal for players with strong embouchure support who perform in high-stakes environments. Giddings mouthpieces stand alone as the premier choice for a true one-piece stainless steel or titanium trumpet mouthpiece — delivering unmatched durability, consistent response, and superior energy transfer from your buzz straight into the horn. The result? A powerful, centered core tone bursting with brilliance, clarity, and projection that cuts through any section while maintaining focus and musical nuance. Available in five versatile cup depths:

• Deep — Maximum depth for the richest, darkest symphonic foundation and enormous volume.
• Medium Deep — Balanced richness with excellent breadth; perfect for anchoring large ensembles with warm, expansive tone.
• Medium — Our most versatile all-rounder — superb core, articulation, and flexibility across registers and dynamics.
• Shallow — Enhanced brightness and slotting for lead work or brighter styles, with quick response.
• Lead — Optimized for extreme upper register power, endurance, and cutting edge.

Available in brilliant Stainless Steel (for maximum efficiency, power, and laser-like projection) and Titanium (lighter weight with a crisp, focused response and exceptional durability). Choose this rim when you need commanding presence, centered projection, and tonal versatility for orchestra, wind ensemble, or big band work. Elevate your sound with the confidence and authority that only a premium one-piece Giddings mouthpiece delivers.
