J 'series uses the Yamaha club in 10 years. Very solid and reliable equipment. No break in 10 years despite heavy use. I tried quite a few models but in this price range that is the best that I found at the time of my purchase (10 years). The higher the price. The least the cuts that they'd better mitigate using a graphical équalo. Value for money very good strength. I remake that choice without hesitation.
