Why Players Love the MB4ET (Extra Traction / Round Rim)
The MB4ET is specifically engineered for players who love the classic flagship GW4 dimensions but want a more forgiving, cushioned feel on the embouchure.
The "ET" Rounded Rim Advantage: The "ET" designation stands for its specialized, more rounded rim profile compared to the standard GW series. This unique profile distributes lip pressure evenly, drastically reducing lip fatigue and maximizing playing endurance during long rehearsals or high-stakes performances.
Massive, Centered Tonal Core: Dimensionally based on the popular 26.00 mm cup size, the MB4ET adds a touch of additional weight to the outer body. This extra mass helps center your slotting and focuses your energy directly into the horn for a remarkably deep, rich, and velvety sound.
Exceptional Versatility: The 7.38 mm throat paired with the rounded rim offers clean front-of-note clarity and flexible articulation, making it a fantastic all-around favorite across all registers.
Specifications:
Shank: Large Shank
Cup Diameter: 26.00 mm
Rim Width: 6.70 mm
Throat/Bore: 7.38 mm
Rim Profile: Rounded (ET Model)
Profile Feel: Compares beautifully as a premium, high-performance upgrade for players who like standard "4-size" profiles like a Denis Wick SM4 / 4AL, Alliance DC3, or Bach 4G.
Condition Report
This mouthpiece has been carefully handled and is in good, performance-ready pre-owned condition.
Rim & Cup: The rim and cup are clean and in good shape, ensuring a perfectly smooth, uncompromised feel on the lips and a normal playing experience.
Plating & Body: The silver finish is in good cosmetic condition, retaining a wonderful shine with only normal, light signs of standard handling over time.
Shank: Shows typical, light cosmetic insertion marks from being placed in an instrument receiver. This is completely standard for any used brass gear, entirely cosmetic, and has zero effect on the shank's roundness, air seal, or acoustic resonance.
Why This Is a Great Deal
1. Significant Savings: Avoid the heavy investment of buying brand new. This is your chance to snag an authentic, top-tier MB4ET at a fantastic used value.
2. No Structural Compromises: Because the critical playing areas (the rounded rim contour, cup, and throat) are in good condition, this mouthpiece plays exactly like a brand-new model straight out of the box.
