RATTLE GUITAR AND DAMPED GUITAR
Two more guitar-like instruments: The rattle guitar on the left has eight strings in four octave-pairs. Each pair has a wire rattle to add a buzz to the tone. This instrument has neither pickup nor much of a soundboard or soundbox. For more volume I usually bolt on a styrofoam ice chest at one or both ends. This adds a lot of sound-radiating surface, increasing the sound output. The Damped Guitar on the right is a fairly typical electric guitar, but with an adjustable damper of sponge rubber positioned at the bridge. This provides a variety of partially damped string effects.
Two damped guitars are heard first in the sound clip, playing a song accompaniment (sans voice). Then comes the rattle guitar, with many other instruments in accompaniment.
