Contrastingly, mass-market archtop guitars became more affordable in the late 20th century, due to a combination of low labor costs in Asian countries and computer numerically controlled manufacture. Most major guitar marques include at least a couple of archtops in their range, albeit not necessarily manufactured at their own facilities. Ibanez sells an extensive range of archtops under the Artcore marque. The Samick corporation sells archtops under its own name besides manufacturing for other companies. Gibson sells inexpensive Asian-made archtops under its Epiphone brand, such as the Epiphone Dot.
