F-Holes

seany65

I've had 3 semis and on all three I've been able to hear a difference when I pluck the open D string and move my hand up and down over the Bass-side F-Hole. This can happen with D notes on other strings that are close to the open D. But I can't hear any difference in any note when I move my hand up and down over the treble-side F-Hole.

So does the Treble-side F-Hole have any effect on the sound?

Does the length and width of an F-Hole have an effect on the sound?

One of my Gretsches used to feedback like mad, amp up full. I made some "pillows" out of pillow/duvet stuffing in black plastic bags and poked 'em in. Soft fluffy stuff, easy to get in/out (foam was too much of a fight, felt like the binding would get damaged, so gave that up).

Result was zero difference plugged in. Maybe my cat could tell the difference, but I couldn't   The strangest thing to me was that even acoustically there was very little change... I thought it would be kind of dead? but it really wasn't.
Also you see those top-dog carved archtops with all sorts of holes, F and multiple leaf-shapes and in different places, so with all that I'm thinking the guitar top is most important and the bracing and the amount of gear hanging on them - pups, Bigsbys whatnot? The jazzboxes strive to minimise all that stuff and have all sorts of arty f-holes.

Ironically, my Chibson has a very noticeable difference if either soundhole is covered... must be the diamonds

Thanks for the replies and the suggestions.

But, just like my sex life, I'm not stuffing any things up any holes.

I get some bloody strange sounds coming out my Manhole too...
