Is this the frequency responce for the finished guitar including the bridge? What type of guitar, steelstring classical? Also the white number are hard to read.

Bridge patch shape suggests its a steel string. Circa 100Hz peak looks like an air resonance peak so this would suggest the top is on the guitar when analysis done.

Hi Wes...did you put the side weight attachment points in to trim body resonances? Your 185 needs to go down 5 Hz to start with and side weight is an easy and effective way to do it. I put them in all my guitars now.

Wes have you done any Chladni testing? Im currently in the process of doing same on my falcate classical.....the discussion may be of use to you.

not yet, guitar has been finished for several months and sounds really good, prototype design i have another in process with falcate bracing so i can compare
