Ive acquired a bass recorder. It's made of Maple wood. It looked as though it hadn't been played for a while. I've been slowly 'playing it in' but noticed that after a few minutes it seems to get blocked and looking through the windway there is a slight stream of moisture running down the top centre of the windway which muffles the sound. Obviously I have to blow this out to get the strong sound back but have to stop playing to do so which isnt good halfway through a piece! Has anyone else got any suggestions how to overcome this? A friend of mine has some product that she puts in the windway to repel moisture???

Thanks

How much did you pay for the wooden bass?

Is the moisture clogging the wind hole or the finger holes? You can try to position yourself so that the instrument is slightly tipped, with the finger holes (and wind reed hole) on the "up" side rather than the "lower side." That way the moisture will run down the back side of the recorder and harmlessly on down. This is sometimes harder than it might seem, of course. Once moisture gets a path going, all subsequent drips just follow that same course, so the objective is to try and not establish that path that runs by the reed opening and the finger holes.

I have a plastic bass and have been having the same problem. I have found that if you warm up your recorder before you start playing, the moisture doesn't condense as quickly as in a cold recorder.
Hope this helps!
