OT: Modifying by sanding the bracing

[Engblom]

This is a bit offtopic from CBG. I got a super cheap (70€) acoustic guitar with great intonation. I am trying to see how much I can improve it. So far I have made bone nut and bridge, adjusted the height of the strings, adjusted the truss rod and changed the strings. It already sounds a lot better but not as good as I wish. It got a lot of treble, but the low frequency response is bad. This is especially noticeable as I do mostly finger picking.

I am considering to try to fix it by reshaping the bracing a bit with help of a sandpaper. Then I could do it by just putting my hand/arm into the sound hole and not needing to take the guitar into pieces. How would you reshape the X bracing to make it more sensitive to lower frequencies? From where would you remove some material?

Thank you for your reply! The sanding of the bracing really did some magic. I might sand a little bit more the next time I change strings. Also now that the retro strings has set in, they do have better sound than when they were completely new.

I normally just do finger picking, but in Open D, instead of standard tuning. In the video I used standard tuning, because that way you are best able to judge the sound. The strings are a bit floppy in open D.
