sa tingin ko safe estimate yung 12K to 50K. why the wide range? custom kase eh, meaning you get to choose what components you want for your guitar, so dependent talaga sayo magiging final price ng guitar mo. suggest ko try mo tawagan yung mga luthiers natin, like jon of elegee guitars or mang max of karisma guitars, they are the ones that can give you the appropriate answers. madami pang ibang luthiers like yung sa arcee guitars, search mo na lang mga threads nila dito for their contact info.
