10 GW Helios Trumpet Mouthpiece Rim Diameter 16.00mm, .630 inches

The Weapon – 10 Rim Diameter. 16.00mm / .630" inner rim. This is the ultimate lead machine — a relatively small inner rim diameter paired with our razor-sharp shallow cup creates a compact, ultra-responsive setup that's pure fire for players who live in the stratosphere. Designed for extreme volume, laser-focused control, and the kind of screaming highs that demand attention, this mouthpiece lets you dominate any chart with confidence and authority. The small rim provides tight, secure embouchure support — giving you the precision and endurance needed for long nights of high-note heroics without the wobble or fatigue. Combined with the shallow cup, it delivers bright, piercing brilliance, lightning-fast articulation, and effortless slotting in the upper register — perfect for cutting through big bands, rock horn sections, studio sessions, or any gig requiring maximum projection and edge. What sets it apart? A slightly larger throat than many traditional lead pieces adds serious impact and core to the sound — you get that massive, centered punch and depth that fills the room, rather than thin or brittle highs. Stainless steel construction supercharges everything: superior energy transfer means your buzz hits the horn with instant power, enhanced durability, and a vibrant, efficient response that stays alive all night. Why lead players love it:

• Extreme upper register power — highs feel open, secure, and effortless with explosive projection
• Uncompromising volume and control — big, bold tone that cuts without losing focus
• Added core and impact — the larger throat brings body and weight for a fuller, more authoritative lead sound
• Fast, precise response — ideal for screaming lines, pinpoint attacks, and dynamic fireworks

If you're chasing the throne in lead trumpet — whether it's Maynard-inspired burns, commercial punch, or modern high-energy playing — this is your secret weapon. Small rim, shallow cup, big throat, massive results. Play louder, higher, and cleaner than ever.
