The signature bass sound that rattles the windows on most Pontiac brand cars. No car can beat that bass. Not even a Chevy which was the same model.

Drop bass or simply “Drop” is the largest, deepest, loudest, and most scoliosis inducing bass drum in the line. This bass is very important for any marching band.

The best and most glorious of the instruments, although ridiculously large and loud. The strings are E, A, D, and G, also known as Death, Ok, Nice, and Good. The bassist's job is to act as a metronome (and to keep the violins from rushing). Be nice to them, they try their best.
Person A: Hey, I just started playing the string bass!
Person B: Good choice. It's totally the best instrument.

An oft-undervalued instrument. Those who play or admire the washtub bass realized that its inexpensive construction and simplicity sometimes distract idiots from the rich variety of notes and tones one can achieve when playing a washtub bass. If one wants to add more dancibility to their band's music, they need to get a washtub bassist, who will most likely have wicked arm muscles. Also know as a gutbucket.
Guy 1: "Man, that chick is hot."
Guy 2: "Aw dude, that's Rachel. Don't mess with her, she's a washtub bassist."
Guy 1: "Thanks bro. Close call. She could deck my ass."
