 For instance, the Vox Continental tends toward having somewhat of a Hammond-like, or "sine wave"-like sound (only thinner); while the Farfisa Combo Compact has an aggressive, raspy quality to some of its boosted tones, and the Gibson G-101 has a cleaner, contoured, more "sawtooth wave"-like tone, with harpsichord-like, percussive sound capabilities and a slight "after-jingle", with Sustain selected, on some voice settings.To collectors, players and enthusiasts, the visual aesthetic is often as important as the sound.Originally, the instruments were often available in bright and unusual colors (orange, blue, bright red, green) with showy chrome legs, multi-colored stop-tabs, and reverse-colored or gray-and-white keys.
