Music Link is indeed their US brand and sales office - Music Link and Shanghai Super Music are the same company. The have amazing purchasing power and quantities and the poor little Tonerider stand was dwarfed by their multistory construction at the Shanghai Music Messe last year! It was enormous! I didn't see daylight for four days. They represent Martin, Squier, Hughes & Kettner, Cort, Johnson and a myriad of other brands in the Chinese market.
Most industry watchers predict that they will import some serious expertise for higher level instruments and create the first Chinese made and owned premium brand a la Ibanez....could be a few years, but it will be sooner rather than later!
