3A Quilted maple is so beautiful looking at times, that you think it has to be 5A. 3A is usually larger quilts and not as uniform in its quilting as 5A - eh? Others who know far more about this than I do, eh?! Then again, someone might have ordered a standard with 5A maple front and back laminates. The pinstripes instead of the purpleheart neck lams -> standard. The model decides the base price, and any options can be added to it.
Example - It is probably common to order a Mark King to get the cocobolo included in the base price and add Series Two options, as it is over $1,000 cheaper than getting a Series II in cocobolo.
