If I were buying all the parts and assembling it, no finish work, I think between 300 and 700 depending on the quality of the parts, and after a good fret job would be fair. It all depends though on what you want to call parts
ok, if you were to do uber finishes, then get that time back as a part cost and charge a premium for the item
solid colors are just bottom line
then neck woods, an exotic gets extra just because
so as said. for a base finish with good hardware and common neck, 300 for a one off build
for a Uber finish with quality hardware and exotic neck, 700
and then there are those builds in between
Now start doing artwork and carved bodies and you just charge what the market can bear.
after all you have to look at it like a business, you need so much a day to cover expenses, and the price per can go down when production numbers go up
you see that in PRS, the guitars actually have gone down in price, it is just that with inflation they look like they stayed the same, but a axe selling for $3200 10 years ago is around $3200 today
and Basically he is selling a parts guitar he makes the parts, uber finish or not, to quality hardware and better than average pickups
