Our take on the Yamaha YCB-623 Professional Tuba

The Yamaha YCB-623 is a 4/4 C tuba with four front-action monel pistons and a thumb-activated fifth rotary valve. Its 18-5/8 inch yellow brass bell and .748-.768 inch bore give it a full, centered sound with the consistent intonation Yamaha is known for. It suits advancing students and working professionals who want a piston C tuba that plays in tune and holds up to daily use. Against European rotary C tubas it trades a darker rotary color for piston response and easier servicing, and it is a common step up from school-owned BBb instruments.
