Compare the five mouthpieces
Five Gleichweit Bb clarinet mouthpieces, each machined from premium synthetic material to identical tolerances — only the tip opening differs.
| Model | Tip Opening | Character |
|---|---|---|
| 10 | 1.27 mm | Entry into open — warm tone with easy control |
| 11 | 1.33 mm | Full, expressive — great for jazz and world music |
| 11-2 | 1.31 mm | Rich body with responsive articulation |
| 11-7 | 1.33 mm | Bold projection, wide dynamic range |
| 13 | 1.40 mm | Maximum openness — powerful, free-blowing feel |
Reeds: Open tips generally want a softer reed. If you normally play a 3.5, try a 3 or 2.5 across the box. Reed strength is personal — treat this as a starting point.
What it costs
| Item | Amount | When |
|---|---|---|
| Test fee — non-refundable, and not credited toward any purchase | $40 | Charged at checkout |
| Outbound shipping | Calculated at checkout | Charged at checkout |
| Each mouthpiece you keep | $245 | Invoiced by email after your return arrives |
| Return shipping, tracked | Paid by you | Paid to your carrier |
We do not charge your card a second time. Once your return reaches us we email an invoice for anything you kept, which you can view and pay securely in your customer account. Keep nothing and there is nothing further to pay — the $40 test fee and the shipping you already paid are the full cost of trying.
About Open Tip Openings
The tip opening is the gap between the reed and the mouthpiece tip. An open tip (1.27–1.40 mm) gives the reed maximum freedom to vibrate — producing a big, warm, resonant sound with expressive dynamic range. Open tips require more breath support but reward you with incredible tone richness and flexibility.
Cleaning and hygiene
Every mouthpiece in the Test Box is cleaned by hand and disinfected before it ships to you, and again when it comes back to us. Five fresh mouthpiece patches are included in the box.
Before you send them back: swab each mouthpiece and wipe it with a soft, damp cloth. That is all we ask — the disinfecting is our job.
Never use hot or boiling water, a dishwasher, an ultrasonic cleaner, an alcohol or bleach soak, or any abrasive polish. Each of these can warp, dull or permanently discolour the synthetic material, and a damaged mouthpiece cannot be returned.
What is in the box
Five Gleichweit Bb clarinet mouthpieces — the models listed above — five mouthpiece patches, and protective packaging.
Not included: reeds and ligatures. Play the Test Box on your own clarinet with your own setup — that is the whole point of trying at home.

Deadlines, returns and damage
| Situation | What happens |
|---|---|
| Your seven days | They begin on the date the package is delivered. Your return must be shipped by day seven — postmarked, not received. |
| You need more time | Email us before day seven. Late returns are handled case by case, and we would far rather hear from you than not. |
| The return is lost in transit | The sender bears responsibility, which is why we ask for a tracked service. Keep your tracking number until we confirm the package arrived. |
| A mouthpiece is missing from the return | It is treated as kept, and invoiced at $245. |
| Scratches, bite marks or other damage | A damaged mouthpiece cannot go back into stock. It will be invoiced at $245 and shipped back to you. Use the included patches and take care with your ligature. |
| Return address | 214 Market Street, APT 404, Brighton, MA 02135 |
