The top resonance is a high B3 253Hz and body resonance B2 123Hz
It's higher than I had hope for, Now I might just shoot for a heavier bridge to bring down the resonance or thin the perimeter to bring down the resonance.
I began to sand the top to bring down the resonance mainly on the lower bout perimeter.
After some vigorous sanding, I manage to bring down a few Hz; still have a long way to go.
After somemore sanding the resonance points didn't change too much and I realise I can't sand anymore.
The edges are too thin about slightly over 1 mm.
Now what I can do is to reach in and shave down the braces but before that I need to consider what other actions to take.
I could try to shave the back braces to increase the back coupling.
The body resonance should be within range but top resonance is a bit too high.
Anyway I think I just do up the binding and glue in the bridge.
If need to I adjust the back bracing to add more coupling.
