Would like to experiment using a signal generator to produce the key of A (440hz). Want to hook the generator to a speaker and place a guitar top on the speaker and cover wood with salt or sand. Then observe the vibration pattern of the sand particles. I am a luthier and have no knowledge of electronics, requesting your help.
Why not use your soundcard with a PC box and one of theese many many soundcard generator software .... (Most home studio recording software also have these generators build in)
I have an imac desktop computer and it does not have a sound card slot. Was thinking about my ipad with a sound generator app and then running it through a guitar amp. Would this work?
Thank you for giving me the idea! I connected my ipad, with a sound generator app, to a small bass amp presto! It worked. Now I have to experiment with the frequencies do determine the best guitar resonance.
