INSTRUCTIONS FOR USE
Take your Fiberreed from the mouthpiece after playing and dry it. It is the best to dry it in the original packing or in a reed case. Do not leave your Fiberreed on the mouthpiece. The corners of the reed tip could bend after longer use in direction to the mouthpiece which would change the response. If this happens anyhow, dry your Fiberreed carefully for instance on a heater or with a hairdryer. The temperature should not exceed 80° Celsius (176° Fahrenheit). After this your Fiberreed should have the original form again.
You can clean your Fiberreed in many ways. Adequate agents are dishwashing liquid or toothpaste. A disinfection with alcohol or an nontoxic disinfectant is possible. We recommend this especially if your Fiberreed was used by others.
After prolonged use…
…it happens that little pieces quarry out at the tip of the reed. This does not affect the sound and the response normally. You may smoothen the reed tip by sanding it with a sandpaper grain 1000 in a 90° angle (like filing finger nails) carefully. Remove as little material as possible (0,5 mm/0,02 inch). Otherwise your Fiberreed will loose its harmony and will get too hard.
ADDjust Vary Support
Harry Hartmann’s Fiberreed in the green box are delivered with a yellow rubber support. This rubber support enables the reed to vibrate more freely especially when the ligature is made out of metal. ADDjust Vary Support is a set with four different rubber supports exclusively made for the model Harry Hartmann’s Fiberreed delivered in a green box. The different rubber supports replace the original. With different degrees of hardness it is possible to control the sound and the playing abilities of the reed. The ADDjust Vary Support set contents two softer and two harder rubber supports. The softer the support is, the lighter is the shade of the yellow, the harder it is, the darker the yellow is. Equally the sound will be softer with a softer support, the sub tone will be playable with more ease. The harder supports cause a more direct tone and improve the playability of the high register.
The rubber supports are equipped with a adhesive film. A reasonable approach to find out which rubber support is best for me is like following: After you have played the reed with the original rubber support once more you remove it. You can simply take it off. Sometimes the adhesive film adheres to the support, sometimes to the reed. Both is fine. Then you can try out the different ADDjust Vary Supports one after the other. The white protection film will not be removed yet. After all five different rubber supports (the four ADDjust Vary Support of the set and the original) are tested and you know which one is the best for you in order to meet your personal sound and desired playing abilities best you can fix this rubber support on the reed permanently. If it is the original rubber support you can just press it against the reed now. If you choose one of the four ADDjust Vary Supports of the set you have to remove the white protection film now. In doing so you have to take care not to remove the adhesive film together with his potection film. Now you can fix the rubber support permanently on the shaft of the reed.
If the adhesive film does not adhere anymore after long use you can replace it with a new piece of standard twin-sided adhesive tape.
