I know bridge placement has been discussed, but what about the difference between the glued on bridge with the strings pegged, or hooked on like a uke or hard tail, compared to a bridge with a tailpiece and the strings pressing down on the bridge.
I know that more down pressure is good(to a point) but what about up pressure. The acoustic guitars with pegged strings would have a pulling force on the soundboard rather than a down pressure. What do you cbg wizzes think of one over the other for acoustic purposes. I'm hoping to have as long a debate here as John got started so lets go.
This thread has been dead for a while but I just now read it so I'll add a little to the list.
If you think about it all or almost all of the guitars today with floating bridges are hollow body arch tops. Most all of the "flat top" acoustics have glued on bridges with the only notable exception being the selmer maccaferri guitars like D'Jango played.
I asked my brother, who is a lifelong arch top player if he ever heard an arch top with a floating bridge sound as good as an acoustic such as a dreadnaught and his answer was no.
On the other hand we can look at violin's that have tail pieces and floating bridges and they can be remarkably loud with great tone. Unfortunately I don't know if anyone has ever made a violin with a glued on bridge, so there is no comparison to be made. Since we are usually putting electronics in our cbg's the point is moot.
I will mention that I was considering some time ago using a sound post directly under the bridge that would connect the top and back just like on the violin. I haven't done it yet but now that I'm making my own boxes it should be easier to do.
He Charlotte, I'd be interested to see the boxes that you make, I can't get decent boxes here so I've started making my own as well Having found a size that I'm completely happy with I've made a forming box so they all end up the same size making it easier to nut out where every thing will go. I'm still struggling with the best wood to use for sides and lids, I've been using 3/16 American oak for the side and 1/8 ceder ply for the top and bottom. I know some ply woods work well on acoustic guitars but feel that over a small airier such as a cbg it is too rigid to resonate so I'm experimenting with making my own one piece straight grain tops.
regards to all
I bought a box joint jig from Rockler that works with my router table and a 1/4 inch spiral cut router bit and I'm making some box sides out of poplar and some out of pine. They both are very resonant when tapped and I'm going to use spruce for the tops and a 1/8 inch craft ply wood for the backs. The craft plywood seems hard enough and nice enough to even consider it for tops. I'm stuck in the process right now trying to decide how I want to proceed with neck attachment, bridge method, etc.
I also have some 1/8" birch ply I wanted to try for a top but have been busy on other projects and need to finish the CBG I've been working on for some months first.
More over thinking
The main thing to remember when building a acoustic is lighter is best and the less wood that is in the box the better it will sound.
