The Hertfordshire Horn Modification |
Incredibly, this enhancement was discovered completely by accident.
It is not recommended for every instrument, but can transform the performance of those which blow too freely at a low dynamic level.
By placing a restriction at exactly the right point in the final bell section, the tone in pianissimo is dramatically improved and quiet note production becomes significantly easier.
 |
Theory
Subsequent research has
shown that the exact placement of the constriction is critical:
For this reason, the circumstances applying to the original modification are rigorously copied. As this has to be preceded by a Trans-Atlantic flight, the procedure is not cheap. |
 |
Cosmetic
To complete the process, a special tape, obtained by us from the aerospace industry, where it is used on the Stealth Bomber, is applied to the modification. Its remarkable reflective properties almost completely disguise the deliberate restriction. Thus your colleagues, marvel as they might at your new found hyper-technique, will never know your secret. |

A Cornet undergoes modification in our workshop where the special cosmetic shielding tape will be applied, thus completely disguising the amazing 'Techno-Dent'.. |
| Warning: Brass instrument repairers in the provinces and even some on the extreme outskirts of the Jubilee Line may well be unaware of the developments in Duffchops cutting-edge modification technology. When leaving an instrument with them for repairs, it is important, therefore, to draw their attention to the fact that your enhancement is deliberate, otherwise they may well de-maximize your instrument by taking out the precious techno-dent (if they can see it). |
