This meeting was held at Mercy Music
I wish this experiment was done on a $25,000.00 data spectrum analyzer using FFT and a shaker system for a complete analysis, but God gave us a pretty accurate data spectrum analyzer called an ear. It is surprising what you can determine just comparing the tonal variations between woods. Besides the 25k unit still has to spit out data that is verifiable by your ear anyway.
Subjects covered in this meeting were:
1. Jim's Rickenbacker Model
730S "Shiloh" was a factory second bought through a special program for
a now defunct organization which shall remain anonymous.
|
 2. Notice the abnormal bridge pin slots designed to apply the same string pressure on the saddle for all six strings. This creates better string balance, even string energy and an equal dynamic force of vibrational energy through the guitar top. |
 3. Jim senses the vibrations as Gary demonstrates the string output balance obtained by the compensated bride pin placement. |
 4. The above is a scribble used in our discussion about frequency transfer through neck joints of various design. |
 5. Doug's effort to make a better neck thru the body Jackson style electric guitar is coming along quite nicely. |
 6. His neck non joint angle is attained by adding a piece to the back of the body portion of the necks through design. |
 7. Steve's Mahogany neck back with maple fingerboard has raised some eyebrows but this combination of woods has been used on Gibson guitar bodies since the fifties. |
 8. This picture demonstrates the problem of to much truss rod depth. if the fingerboard was glues on now the rod would rattle. |
 9. We spent some time rapping about the various tonal possibilities to be gained by using different exotic woods. Then we spent some time rapping on the woods and listening to the the large variations of resonant frequencies. |
 10. Gary decided to rap on John for a final test. Jonathan resonates at a type "A" personality. |
