Edward; My 1970 Rubio developed a terrible rattle internally due to detached bracing. Guitars routinely have bracing repaired through the sound hole, but lutes require removing the top. Major surgery, but it was done successfully on my lute. Good luck. My repair was done by Mel Wong in San Francisco.

I've noticed the maker didn't remove the paper stencil(?) after carving out the rosette and closing the instrument, so the paper is still glued to the underside of the rosette. I'm wondering if that might be contributing to the buzz. Is it common for makers to keep that paper stencil/pattern on the instrument?

Try holding the instrument with your fingers on the underside and with your thumb go round the edge of the soundboard applying a LITTLE pressure to see whether there are any noises of the soundboard moving against a bar (like a little click probably). You can also tap lightly on different areas of the top with the tip of your middle finger to see if there are any unwelcome noises. Obviously do this as gently as possible. Have you checked on the relative humidity? If you have a concert coming up and you think there is a loose bar, make sure the relative humidity is at least 50% (but no more than 65%) and this might resolve the issue temporarily.

I have a renaissance guitar and there's a buzz that starts with the plucked note and dies down quite quickly. I've checked the bridge for any loose bits of string - nothing. I've checked the pegbox/peghead for loose buzzy strings - nothing. No possibility of frets being too high and buzzing, as the buzzing happens at all notes at all positions. I'm hoping it's not something beneath the soundboard that's loose and causing the buzz. It doesn't buzz when the instrument is flat, with the rose facing up. It buzzes when the instrument is in a playing position - with the rose facing sideways. It buzzes with the rose facing down. I'm on the verge of having this sent to the nearest luthier, but have a performance coming up. I just hope the audience won't be able to hear the subtle buzz, as we're not being amplified⦠Best, Edward To get on or off this list see list information at [8]https://urldefense.proofpoint.com/v2/url?u=http-3A__www.cs.dartmo uth.edu_-7Ewbc_lute-2Dadmin_index.html&d=DwIFaQ&c=l45AxH-kUV29SRQusp 9vYR0n1GycN4_2jInuKy6zbqQ&r=VLPJ8OE-c_C6joGeE1ftlvxMmQPq9N6mpKZONBRt 90E&m=ygKsLc2OUpQjhhRUgTCOR5Grvb2h2JLCNWSfi5Lok3k&s=Mzh2XPos7rE0Tjjy iKx0rRkX03f0IwqU2Mxp8MQDWnA&e= References 1. mailto:edward.y...@gmail.com 2. mailto:heiman.dan...@juno.com 3. mailto:lute-...@cs.dartmouth.edu 4. mailto:lute-...@cs.dartmouth.edu 5. mailto:edward.y...@gmail.com 6. mailto:lute@cs.dartmouth.edu 7. mailto:edward.y...@gmail.com 8. https://urldefense.proofpoint.com/v2/url?u=http-3A__www.cs.dartmouth.edu_-7Ewbc_lute-2Dadmin_index.html&d=DwIFaQ&c=l45AxH-kUV29SRQusp9vYR0n1GycN4_2jInuKy6zbqQ&r=VLPJ8OE-c_C6joGeE1ftlvxMmQPq9N6mpKZONBRt90E&m=ygKsLc2OUpQjhhRUgTCOR5Grvb2h2JLCNWSfi5Lok3k&s=Mzh2XPos7rE0TjjyiKx0rRkX03f0IwqU2Mxp8MQDWnA&e=
