Post subject:  calling all tappers, opinion requested

o.k. I think my top has a nice ring/sustain going when tapped with a hammer ,, as far as the back goes ... when I hold the braced back by pinching the carved end of the brace closest to the neck , and tap it between the two lower bout braces I get ( what sounds like ) a nice tone then a soft rumbling decay , it seems to be sustaining even longer then the top... is this a good thing ??? is maybe my back too loose ? I am not sure what anyone is looking for ( or listening too) when tapping the back ! any help is appreciated , thanks , Jody

P.S. the back is mahogany and it is thicknessed , lower bout ,at about .103. most of the upper bout is still about .110 .

I'm with Laurent, what do you mean by "tapped with a hammer"

Eat Drink

Kinda makes me think of that record from the early nineties 'Please Hammer Don't Hurt 'Em'

lots of things are a bit strange about what you wrote.

.103 for the back in the lower bout / .110 in the upper; I gather you are telling us that you are voicing the back by scraping the thickness. .110 thick back is about .010 thicker than most mahogany backs I have done.

Tapping with a hammer I hope you mean a piano hammer and not a carpentry hammer.

Hello, yes its a felt headed tap tuning hamer , I am saving the 32 oz, framing hammer in case I need to make some " adjustments" when I am finished with this one wow7-eyes ,hence all the questions , laughing6-hehe and yes I have been thinning the back at the lower bout some by sanding ..... I am not realy sure what to look for when adjusting the back.... I bought another back set of mahogany just in case i dont like the projection of this one .... thanks Jody

I think you'll get better information by tapping with the tip of your fingers…
Flexing in all directions and running my fingers on the wood probably tell me more than tapping, but that's me…
You may want to hear clear individual notes by tapping the back behind each brace.

Stop listening to the note, and start listening for the tone......

And toss the hammer. Give it the finger...... laughing6-hehe
