Hidden away in one of Rosario's busiest pedestrian areas is Luthería del Pasaje. There, Ivan Blascovich has balanced the restoration and creation of acoustic instruments since 2005. 

"One needs an aptitude—one needs patience, dedication, in order to make a great instrument," Blascovich said. "You can't make something quickly."

One guitar can take between 300 and 400 hours to build and most, if not all, of the work is done by hand. Generally, an order through Luthería del Pasaje will take six months to a year.
