Funny thing, I called that dealer because my Vib. has a problem with air leakage probably coming from moisture (sometimes the lower octave sounds with the higher when I play louder although the valve of the lower octave is definitely closed – and it doesn’t work the other way round!). I really don’t understand why the Victoria people didn’t use a wood that is usually taken for woodwind instruments, such as grenadille or cherry wood. And why they leave the wood compeletely untreated instead of at least staining or lacquering it. Perhaps it will sound a little less warm then, but I’m sure the difference will be negligible. Or why they didn’t learn from the accordina manufacturers who build an air chamber of plastic into their wooden instrument.
