Hey! The very first guitar I made had a pine top, salvaged from an old door. Unfortunately (perhaps fortunately) it went on a bonfire a few years later. One day I might try and recreate that guitar, if only for the sake of nostalgia.
The 'solid pine top' you mention may well have been spruce. Sometimes people interchange the terms. Then again it may well have been a pine top.
Bouchet's very first guitar had a pine soundboard. It does seem to sound a little different but not in a bad way. I quite like the sound of it.
Visually the soundboard certainly has the look of pine, wide grain. What we would call a grade C soundboard. Tonewood dealers stop at grade B.
