tailpiece

The sink stopper and the control rod that makes the stopper go up and down are choke points within the tailpiece pipe just under the sink.

One benefit of removing the stopper is you can clean the sidewalls of the drainpipe tailpiece that extends from the sink down to the P trap under the sink.

For the solo, John simply wailed on the guitar, executing a series of power chords as Douglas, sitting nearby, reached over and worked the instrument's Bigsby tailpiece.

You can also unscrew the nut on the back of the tailpiece, remove the lever that lifts the stopper and clear out all the obstructions.

The string section—violins and violas, cellos and basses—are composed almost entirely of carbon compounds: Wooden belly, fingerboard, sound post, pegs and tailpiece; gut strings, horsehair bow and plastic chin rest.
