Instrument pics, as promised, Carlos . . . feel free to resize as warranted.
On the guitar, I didn't do more than a modest pore-fill & light amber tint in the sealer coat as I wanted to emphasize the warmth of the natural mahogany. The maple neck/headstock took on a slight amber tone just from the multiple coats of poly.
The uke has no pore-filler or sealer, only multiple coats of poly on the zebrawood, binding, and the mahogany neck/headstock.
