Any advice to help me restore the tone to my 1974 D-18 would be greatly appreciated, thank you.
I have inadvertently tinkered with its innards to the point where it now sounds airy with no meat or body or fullness to the sound. And there’s too much empty open flat echo inside. I have tried different strings to no avail and finally had to accept that the problem lies within the box.
Here’s what happened (he said hanging his head sheepishly…): Over time I have been sanding some of the straight top braces to resemble scalloped and the two rear bottom braces to reduce their height. Up to this point these efforts had produced a nice fuller sound with more bass.However, the other day I hit a tipping point. I sanded more of the top braces, and used a contoured form to sand down more of the rear bottom braces. I also used a small very sharp chisel and sandpaper to remove about 50 percent of the popsicle brace at both ends, but not in the middle. When I restrung I had lost the full round warm sound I once had.
