Before You Play ■ Assembling the Leadpipe (Sousaphone only) The sousaphone uses a multi-piece leadpipe. This leadpipe in combination with a bit allows the player to adjust the mouthpiece to a comfortable position to best fit individual needs. 1. Apply some slide grease to the middle section of the leadpipe and then insert it into the leadpipe receiver. Next, tighten the screw on the receiver to secure the middle pipe in place. Leadpipe Bit Middle pipe ■ Assembling the Marching Tuba (Marching series only) The leadpipe on one of the marching series tuba models can be switched to convert the instrument between marching use and regular concert use. (An "M" at the end of the product number indicates a marching series tuba.) 1. Loosen screws A and B to remove the regular concert leadpipe, then attach the marching leadpipe and tighten screws A and B.
