Detail 01
.690" cup diameter (17.52mm)
A large rim. More lip inside the cup means fuller low and mid range, but you tire faster without a built embouchure.

SchilkeHeavyweight Series Trumpet Mouthpiece in Gold 18 Gold
Independent shopping perspective
The Korena take
Schilke's heavyweight-blank trumpet mouthpiece in the model 18 size — a large .690" cup for players with a developed embouchure who want a fuller, darker slot.
Strong match
Who this is for
- Established players moving up from a .670"-class cup
- Orchestral and big-section work where tone weight matters
- Players who want more mass behind the sound
Consider the trade-offs
When to look elsewhere
- Beginners — .690" is a lot of rim to control
- Lead and screamer playing; the deep C cup fights the upper register
- Players chasing endurance on long high sets
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Rim high point near the center
It plays smaller than .690" suggests. Slotting feels more secure than the raw diameter implies.
Detail 03
26 throat
Schilke's standard bore. Free-blowing without being wide open — resistance stays predictable across registers.
Detail 04
Heavyweight blank
Extra brass mass around the cup. Slower response, more core in the sound, less spread at high volume.
Detail 05
Gold plating
Softer, warmer feel on the lip than silver. The usual pick if silver irritates your skin.
Detail 06
Standard cup and backbore
No shallow-A or tight-a shortcuts. Tone production comes first; the upper register is on you.
Final check
Know before you order
- 01Mouthpiece only — no case, pouch, or brush
- 02Confirm your horn takes a standard Bach-taper trumpet shank
- 03Heavyweight blanks feel different in a leadpipe; expect an adjustment period
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How is this different from the regular Schilke 18?
Same cup and rim dimensions, more brass around them. The heavyweight blank adds mass, which darkens the core and slows response slightly.
02Is the 18 good for lead playing?
No. The large diameter and standard C-depth cup favor tone and volume. Schilke's A-cup models with the tight a-backbore are the lead designs.
03Gold or silver plating — does it change the sound?
Feel, mainly. Gold sits warmer and slicker on the lip. Choose it for comfort or if silver bothers your skin.
04What is a 26 throat?
The bore size at the narrowest point of the mouthpiece. 26 is Schilke's standard for the medium-to-large models — moderate resistance, even response.
