The placement of the pickup greatly affects the sound, timbre and tone of the instrument. A pickup near the neck joint emphasizes the fundamental and low-order harmonics and thus produces a deeper, bassier sound, while a pickup near the bridge emphasizes higher-order harmonics and makes a "tighter" or "sharper" sound. Usually basses with multiple pickups allow blending of the output from the pickups, with electrical and acoustical interactions between the two pickups (such as partial phase cancellations) allowing a range of tonal and timbral effects.
Fender's Bass Guitar is right at the top of the market, thanks to its robust, buzz-free sound and excellent playability. It features a classic light wood finish that looks great and a graphite-reinforced neck. It also comes with responsive, lightweight tuning pegs that won't slide out of tune easily, as well as a real high-quality bridge that doesn't buzz.
Sheet music from the 1920s provides evidence that the drummer's sets were starting to evolve in size and sound to support the various acts mentioned above. However, the first "talkies" or films with audio, were released circa 1927 and by 1930 most films were released with a soundtrack and the silent film era was over. The downside of the technological breakthrough was that thousands of drummers who served as sound effect specialists were put out of work overnight. A similar panic was felt by drummers in the 1980s, when electronic drum machines were first released.
Portable digital pianos, for the sake of lower production cost, were often equipped with a less complex system for the weighted keys. As a result, the feel of the keys is usually much less realistic than other digital pianos. However, it still retain the emulated weight mechanism (lower keys are heavier than higher ones), though not as precise as more expensive pianos. However, certain models include synthetic ivory-like keys as opposed to standard plastic keys.
Since there are so many digital pianos worthy of your attention in this catalog, you may want to narrow down your choices using some of the search options on the sidebar. For example, if you select stage digital pianos under the category section, you'll be presented with all the digital pianos that were made for the stage. Once here you have the opportunity to drill down even further and can search by topics like number of keys, MIDI/USB Connections or by whether or not the digital piano has built-in speakers.
