GWC-958 Lead Trumpet Mouthpiece – The Ultimate High-Altitude Weapon
Inner Rim Diameter: Smallest in the GWC Series | Cup Depth: Chocolatero-inspired | Throat: .232" |

This is the one you've been waiting for — the GWC-958, engineered for players who live in the stratosphere and refuse to compromise. With our smallest inner rim diameter, it delivers razor-sharp control, pinpoint security, and that locked-in feel that makes extreme highs feel like home turf. Paired with a cup depth inspired by the legendary Chocolatero (rich enough for core and bite, shallow enough for lightning speed), and a tight .232" throat that compresses air into pure laser-focused power, the 958 is built to dominate:

  • Extreme upper register access — Highs slot effortlessly, scream with clarity, and hold forever without wobble or fatigue
  • Surgical control — The compact rim gives you unmatched precision for pinpoint attacks, fast articulation, and dynamic fireworks in the altissimo
  • Big band & commercial punch — Cuts through roaring brass sections like a blade, with brilliant projection and that signature "zip" that demands attention
  • Endurance for the long haul — Smaller rim + efficient stainless steel = less pressure, quicker recovery, and the stamina to burn all night
  • Responsive & alive — Instant feedback from your buzz, shimmering overtones, and the edge that makes solos pop and charts explode

Stainless steel amps every ounce: maximum energy transfer, hypoallergenic comfort, and durability that laughs at endless gigs. No mud, no compromise — just pure, screaming lead tone that says "I'm here, and I'm in charge”. For the player who refuses to be buried in the section — the one who lives every moment to be heard — the GWC-958 is your ticket to the top. Small rim. Big attitude. Maximum altitude. Light it up. Own the sky.
