Inner slide The chrome-plated, nickel silver, drawn inner slide is very durable and has a quick, sensitive response. Outer slide The one-piece, drawn, yellow brass outer slide maintains an accurate diameter throughout its length, and this type of construction ensures, airtightness, smooth action, and exceptional durability and adds resonance to the sound. Inner slide stockings Specially designed one-piece inner slide stockings guarantee airtight slide construction, offer smoother slide action and better alignment, even in the extended 6th and 7th positions. Refined F-attachment The traditional Yamaha style semi-open wrap yields airflow throughout the F-attachment. Upgraded bell materials A gold brass bell provides a rich sound and flexible response usually reserved for professional models. Weight distribution Players are more comfortable playing the YSL-446G trombone because its superb weight distributions makes it easier to hold. Laser-fused pluzuma welded bell A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous even vibrations. Slide lock The unique slide lock design on all Yamaha trombones keeps the slide locked in place and keeps it from accidentally falling. |
