Hi All,

This is the Archtop I just completed (Need some final touches, like a truss rod cover, tuning peg alignment etc). The top is Sitka Spruce, and the back and sides soft maple...Cocobolo for the tail piece and the pick guard...Had to sttring her up to see how she sounds...

The entire guitar was machined on my CNC machine, including the carving of the tops. The top has integrated braces, which were just machined as a one piece on the CNC. It sounds and plays great. The inlays are curly maple for the peghead, fretboard and the tailpiece. This was a bit of an "experiment" with the integrated braces, but I think this is the way I am going forward from now on...Finish is Nitro Lacquer....

Beautiful work Cyborg! I love the finish. How many coats of lacquer?

It looks great! But did you tap tune the plates? This is very important for maximizing the tonal potential of the guitar. It can't be done by CNC. Tap tuning is hand tuning and it makes all the difference between good tone and awesome tone.

Do a search for my other threads here, and you
Will see what was done... Not only was the top tunned,
But spectral graphs were taken to compare the sound
Between that, and one with glued braces...

Thanks for your comments...

Cool. I'm glad you did the tap tuning so as to maximize the performance of the guitar.

You did a fine job on that one. I'd love to hear it someday.
