★J.Michale TR-300S This instrument was designed by the Japanese musical instrument import company Mac Corporation and manufactured in a Chinese factory. Even Yamaha's standard class instruments are made in Indonesia, and many parts are manufactured in China. Bach's TR series for students is also made in China. Nowadays, if the design is solid and the seller has a good quality control system, the country of manufacture doesn't matter. Mac Corporation also develops the "Brasspire" brand for professional players as a higher-end model of J.Michale. This instrument, like the "Brasspire" BPTR-770S, has a reversed tuning slide, a reversed 2nd slide, and a fixed-type finger ring on the 3rd slide. These customizations allow it to have the same specifications as a professional model. In addition, the position of the saddle-type thumb hook on the 1st slide has been corrected to improve operability and hold. The valve casing is no longer directly gripped, and the sound has also improved. The J.Michael, which has been precisely adjusted, sounds surprisingly good. It is comparable to domestic brands. ★Customization Details ・Rebuilt with a reversed tuning slide ・Corrected the position of the front bell brace ・Corrected the position of the thumb hook on the 1st slide ・Rebuilt the 2nd slide to a reversed type ・Replaced the movable ring on the 3rd slide with a fixed type ★Condition ・Silver plating remains at approximately 95%.
