Here's a recently finished instrument delivered to Acoustic Music:Acoustic Music

Scroll down and click on the link for the Berkowitz JB-28C (their database doesn't allow for a direct link to the page).

David,

Gorgeous instrument! Pinless bridge is also very nice, I like that look.

Oh ya, do you mean practice? I just hope I am doing the "right" practice!

Very Nice work David.

Here's a Koa guitar I am finally finishing for a customer in Texas.

David, That is class!
28.59" scale, I thought it looked a little long.
What led you to choose the scale?
John, Nice, real nice!

Jeff, the bridge is my design, but thankfully after all this time, Mr. Kett's excellent execution. I used to do those by hand and it took FOREVER.

Wade, the scale length came out of my dissatisfaction with 28.3" as my smaller baritone scale length. As you go up in scale length the string choices get tougher because you're crossing the threshold between string gauging and the difference between core size and wrap and how one gets to a particular gauge. At 28.3" I wasn't satisfied with the string behavior so I nudged the scale length up a bit. It really sings there.

Don, the finish on this instrument is KTM-9 and yea, I can get it to look right but it's just not hard enough. So I'm experimenting with several options all of which are catalyzed. I found myself chasing finish scratches and other issues that I just couldn't spend anymore time redoing finishes. So I'm throwing in the towel for the time being. --db

Dave, great work. How did you get that tight bend?


John How -- I really like the micro curl on that koa. I would like to see a closeup shot of the radiused joint between the back stripe and the binding. Excellent work

John

Thanks John, Steve and all
Here is a link to a pis that shows the corners. Thew corners didn't come out quite as invisible as I would have liked, I guess that's the way it is with maple. The picture is too big to post on here. But look at it here
Next time I try this I'll use ebony as the binding.John How38429.4138078704

Maple shows EVERYTHING and you did well! You are right about ebony binding. It hides everything.

Looks like a tapered guitar to me or is that just camera angle.

28.59? What an unusual number. WHy not 28.6? It's easier to remember. I doubt that I could hear or feel a difference of .01".   Ahah! I think I get it. 28-19/32 = 28.59375

John,
Why did you decide to use filler pieces for corners instead of making 1 piece?
