El Burdo -> RE: Tap Tones (May 9 2013 15:48:17)

This is depressing. Tap as I might (with a rubber mallet on the board below the braces, or on the harmonic bars), I keep getting a note between C and C# (68Hz). This is for a fully braced, barred and rosetted soundboard. If I am extremely gentle I can just about produce a note near F (43 Hz!) but it's very faint - i.e. I can't hear it, but the tuner senses it. In general, the sound is quite muddy and the resonance short lived, completely NOT like Sn. Somogyi or an audio file referred to on this forum. All these frequencies are below the bottom E on the guitar! The top is Spruce (from 2011), between 2 and 2.3 mm thick plus the odd edge 'effect' of 1.8mm[;)]. The braces are 6 x 3.5 roughly. As I'm doing this by inexperienced hand it's only as precise as I can get it. Any ideas? I've read that the tone is lowered as material is removed so it would seem I have gone way too far - but it's really not that bad (as they say). Er..dirty mark, oil on clamping caul. Tape - gluing splintered edge together. Thanks.
