This was completed a few years ago. Jumbo Acoustic Guitar made of Mahogany, Cedar, Indian Rosewood, Ebony, Koa. Custom inlays of pearl include the owners signature on the back of the peghead, custom Sun Rosette inlay of Koa and Sapele. This is a powerhouse of a guitar with a big sound. A fun project.

Really, really nice work Philip. I have great respect for people who can build musical instruments. That doubles if they can play them too. Congrats

Beautiful work! Would love to try one!

Pics are rather dark. The center stripe on the back of the neck is rosewood, right? Is it bordered w/ curly maple? Do these laminated necks have better dimensional stability and strength for resisting warping from string tension? I am partial to ebony fretboards.

Man, great work…

Thanks for posting!

I,m a little confused as to what picture is showing in the bottom right corner?

It’s so obvious that you know what your doing as this instrument screams “Awesome” and surely deserves everything that was put into it. None of my business but what does a person pay for an instrument like this one?

It’s stunning. This may be a stupid question but how does cedar compare to sitka spruce in the sound board? What kind of cedar is it? Does laminating an exotic to cedar, on the sound board affect the sound?

This instrument literally “screams” quailty

The bottom right pic shows the seam between the sides of the soundbox, on the extreme of the guitar body that’s closest to the bridge. I don’t know what the name is for this particular point. He inlaid some koa in a wedge-like pattern there as opposed to the typical thinner binding that goes there joining the tow bent boards that make up the sides of the instrument. I think I’ve seen that wedge-shaped inlay in more modern, high-end instruments. Not sure this post helped any, LOL!

Also, wanted to tell you I’ve seen some of your projects and WOW! One of the many inspiring project galleries here!

Thanks to all the responses. I’m an amature builder but hope to make a living at it someday. Maybe in 5-10 years I can quit my real job and give it a go. Its a fun hobby right now, I guess more of a passion really. It comes easily to me and its a ton of fun to create these babies.

To answer your questions:
Millo, the laminates on the neck are mahagany/maple/east indian rosewood/maple/mahagany. Some would argue that the laminates don’t help much in the way of support due to the fact that under the fretboard we have to route out a channel for an adjustable metal truss rod that does all of the work, so by the time that channel is cut there is less than 1/2” of laminate left. But personally I believe it does help, plus I love the way it looks.

Moron, Millo is correct. This inlay in the rear of the instrument is what we call a wedge. Its there mostly to cover the butt joint where the two bent sides come together. Its a nice area to put some detail, so I usually treat this area as an opportunity for something unique and fun, same goes for the rosette (the area surrounding the soundhole)

That is another beautifull guitar. I really like it, and would love to hear it. Love your attention to detail. Keep up the great work. How many intruments have you created?
