UK Investigates Casio, Fender, Korg, Roland and Yamaha on Suspicion of Price-Fixing

The Telegraph:

The inquiry is thought to be focusing on whether any attempt has been made to manipulate sales of musical instruments and pro-audio equipment with, among other things, price fixing or controlled sales to specific areas of the country. 

A music industry source said as many as 10 CMA [Competition and Markets Authority] staff visited the offices of the music manufacturers, some carrying out searches for up to four days. Meanwhile, 14 leading music shops have been asked to provide details of their dealings with the companies. The shops are not under any suspicion of wrongdoing. 

The sale of musical instruments and sheet music in online and from shops is worth around £500 million a year in Britain.
