AR Resonance First Aid Euph. Brass Silver

I mounted the device on the leadpipe. At first, I used both fixing rubbers, which greatly dampened the instrument’s resonance. You could say the instrument couldn’t really be blown through. Then I used only one fixing rubber. This way it provided brutally good resonance. The difference is definitely noticeable when using it. Playing with it is stable and pleasant. It’s probably a simple “primitive” device, and also rather expensive, but for anyone who wants to get the absolute maximum out of their instrument, I highly recommend it.
