I'm looking for some advice. I'm building a guitar for a buddy of mine. He's got koa fever so I picked up a nice set from Volcano in the swap meet. Here's where I need some help. I've built 7 so far, but they've all been for me. I like smaller bodies and play a little finger style and flat pick with a fairly light touch. He, on the other hand, likes dreds, light guage strings and he mainly flat picks using medium picks. But he plays with a VERY VERY heavy touch. I would think a dred or a jumbo would probably be the best body type for his style, but what kind of sound board? My initial thought would be that addi would respond best to a heavy touch (or certainly better than something like cedar). What about bracewood? Would you go with scalloped or parabolic braces? I don't think he's expecting it to sound just like a D28, but I want it to be in the ballpark and I want it to be able to stand up to his heavy picking. Any thoughts?


Thanks,


Bob K

Bob,
I think a dread with Adi top and braces would be great for this guitar. Scalloped or parabolic, it doesn't really matter. I'm going parabolic now just because I can't figure out why scalloped braces make any sense from a structural point of view.

Thanks Steve, glad to know I'm thinking along the right lines.

Dreadnought body, Adi top, Adi brace wood Parabolic braces only scallop the x and tone bars as needed for voicing. give a little extra sting stand off for his heavy picking. Maybe 1/64' extra or a little less

Michael, would you inlet the bottom ends of the X into the linings or taper them off until they're flush to the soundboard?

I taper to zero at linings now but use to inlet the x for alignment reasons. My feelings now days is the two wood sweal and contract at differnt rates so I no longer illet any brace into the linings. but do leave the length all the way to the linings on UT graft and X brace.

His hard attack will not affect the top structure IMHO

Hey Bob...you're livin' in my world now.    You got the right idea...adi top, scalloped bracing (ala Martin), and if he has that kind of heavy attack, why isn't he playing with mediums?

Anyway, if I can help on the dread stuff, let me know.

Bill

PS: Let's eat again sometime.

Thanks for the help guys.


Waddy you're not known as a man of few words so that one had me stumped.


Bill, I think he uses lights so he doesn't rip the bridge right off the guitar. Lunch would be great - maybe sometime in the next few weeks if you're free. I could sure use input before I start this project.

Sounds good. I'll call you, and we'll hit one of the local spots near your house. Last time I was there, me and Joe Herrick ate at Lupes. Good grief that's good food.

Yeah, and it sure is easy to eat too much there.

I have been stuck building dreads lately and right now I am on my 9th in a row. All have been for people that like the same things your client likes. By far, I have found that the adi top with parabolic bracing has been the preferred sound they are looking for. I also use a variation of Mario's magic tone bar, which adds some volume to the guitar without becoming brash in tone.


I feather out my braces also, as mentioned above.

Not wanting to hijack the thread here, but are you guys saying that no brace whatsoever is inlet into the linings? If so, that sure would make life easier.

Allen, on my smaller guitars I inlet the all the braces in the upper bout but feather out all the braces in the lower bout. It keeps rigidity where it's most needed but loosens up the lower half of the soundboard. (I inlet all the braces on my backs.) I believe it's fairly common practice, but I've never built a larger body guitar and wanted to check.


Hope that helps.


Bob
