For Jari - Measuring Top Resonance
OK as I mentioned I've tried various ways, but what I really want to do is to feed a frequency signal, through a small amp to a coil to a small rare earth magnet stuck to the guitar top during the various phases of production. Here's a picture of Brian's setup, except now I know that he's using a magnet and coil, not a speaker. That way, the speaker is not part of the equation, you are exciting the top directly and it acts like a speaker
What I need help with is what kind of coil I can use to excite the top. Everything I've tried so far gives a very messy tone, not a nice clean tone at the desired frequencies. I know that with the right coil it will work.
