Euphonium valve gutter

Tired of your euphonium leaking all over you when you play too fast? Well I have designed a 10 gram solution which solves all of it just simply slot it underneath the valves and then from there slide it towards the smaller holes on the top you will hear a click when it is in, revers this process to remove the valve gutter. If this does not fit your euphonium let me know in the comments and if you send me dimensions and a the type of euphonium and I will try to get another version up that will fit your instrument.FINNAL NOTES PLEASE READ if you have a euphonium where the bottom of the valves are flat this attachment will simply not work it needs the little parts that stick out. Other than that I have nothing else, Enjoy!
