The 15,000nt guitar that I am selling is 15,000nt because I’m freezing the design to something that’s more standard, automating whatever time consuming tasks I can in order to build a guitar that requires less manual input from me, so that I can sell a guitar that meets people’s budget rather than me charging 80,000nt starting for any old guitar. Customers may opt for cosmetic or functional upgrades (such as a cutaway, bindings, or other embellishments) for an additional cost.
No custom luthiers would build a guitar for 15,000nt. Unless you want them to work for free.
The reason there’s a 20,000nt premium is because I can’t use standard necks that I can buy pre made, the neck must be made from scratch, as a 12 string neck is wider, AND since you need 12 tuners, the peghead must have space for that many tuners. You can’t just slap extra strings onto a neck.
Or I can do a custom build at my usual custom build price, which is 80,000nt. Then I’ll build you a 12 string for the same price, and I’ll even include cutaways. It will have bindings, purfling, and there will be a list of back and side woods that you may choose from that’s within reason (basically nothing really expensive, so right now that’s purpleheart, padauk, indian rosewood, mahogany, Ovanko, and zebrawood) as well as AAA grade top (I use lower grade top in the 15,000nt guitar). The fingerboard and bridge will be ebony rather than rosewood.
Here’s a guitar I delivered to a customer for 80,000nt: Shipping was another 15,000nt which he paid. It went to the states
He had the upgraded tonewood, the back and side is Taiwan acacia.
