I'm wondering.....(and can't seem to find an answer anywhere) I'm thinking of making my next guitar a bit larger at the lower bout . .... well I have all this cedar that would work fine for the Martin Parlor, but I want to try the Larivee dimensions next time. Is it OK to have three board glue up for a cedar top? Will it have any affect on the end product? . . . . thanks |

Instead of 3 boards I'd recommend adding 2 small wings to the lower bout. You can use pieces from the waist cutout so it will match. I've done a couple adi tops this way...with full disclosure to my customers. You can't see it when they're done. I'm talking about an inch or less on each side. I guess you could use a bigger piece if necessary. |

I like to slip the piece down from the upper bout to the lower to widen the lower as required - that way if there is some runout, it will be the same, and there shouldnbt be a light/dark line running where you added on. Mark them a and b before you cut them .. then you cant go wrong. |

However you do it, mark the pieces so you know which way the runout goes, as Tony suggests. A "runout angle mismatch" can be really noticeable under a finish. |
