Piezoelectric pickups (also called "piezo" pickups) are non-magnetic pickups that use a transducer to convert vibrations in the instrument's body or bridge into an electrical signal. They are typically mounted under the bridge saddle or near the bridge and produce a different tone from magnetic pickups, often similar to that of an acoustic bass. Piezo pickups are often used in acoustic bass guitars to allow for amplification without a microphone.
Sample-based digital pianos do have limitations on the faithfulness with which they reproduce the sound of an acoustic piano. These might include the lack of implementation of harmonic tones that result when certain combinations of notes are sounded, limited polyphony, and a lack of natural reverberation when the instrument is played percussively. They often lack the incidental acoustic noises associated with piano playing, such as the sounds of pedals being depressed and the associated machinery shifting within the piano, which some actually consider a benefit. These limitations apply to most acoustic instruments and their sampled counterparts, the difference often being described as "visceral". On an acoustic piano, the sustain pedal lifts the dampers for all strings, allowing them to resonate naturally with the notes played. Digital pianos all have a similar pedal switch to hold notes in suspension, but only high-end models can reproduce the sympathetic resonance effect.
The digital piano is a specific kind of electronic keyboard that acts as a compact and lightweight alternative to a standard piano. Today's digital pianos feature hammer action keys (88-key being the norm) to emulate the sound and playability of their acoustic counterparts very accurately; some models can even replicate the sound of a pipe organ, Hammond organ and harpsichord. They have many other advantages as well: digital pianos are more affordable, their volume can be controlled and they never have to be tuned. Most digital pianos even have a headphone option for musicians who live in apartments where volume might be an issue. Because of these many benefits, digital pianos are often preferred over acoustic pianos by music educators and their pupils - this includes for amateur performances and school recitals.
The Yamaha falls a bit short on sound quality, though. It offers 10 sounds, but as Brent (who owns a P-45) put it, only three are usable: Grand Piano 1, Electric Piano 1, and Vibraphone. The Grand Piano 1 sound is the only one that has a button on the console for selection (it doubles as the Function button). The others are selected the same way as with the Casio—with a hold of the Function button and the press of a piano key—but the sounds are all assigned to the lowest octave on the keyboard, so you have to look and reach to the far left of the keyboard to change them.
In most genres, a "clean" bass tone (without any amplifier-induced "overdrive" or "distortion") is desirable, and so while guitarists often prefer the more desirable distorted tones of tube-transistor amplifiers, bassists commonly use solid-state amplifier circuitry to achieve the necessary high output wattages with less weight than tubes (though smaller tubes can often still be found in the low-power "preamplifier" sections of the system, where they provide a warmer, smoother character to the bass tone for relatively little additional weight). A few all-tube bass amplifiers are still available, notably from the Ampeg brand.
The Alesis Recital Pro is $100 less expensive than our runner-up, but it doesn’t sound that way. The built-in sounds are good, and with its touch buttons and LCD readout, the keyboard is the easiest and most intuitive to use of our picks. It doesn’t come with a sustain pedal, so it will require an extra purchase of about $20 to make it fully functional. Although it doesn’t sound quite as good or play quite as well as our main pick, it’s clearly the standout value.
Some digital piano implementations, like Roland V-Piano, Yamaha MODUS, Casio Celviano Grand Hybrid, and the software-based Pianoteq, use mathematical models based on real pianos to generate sound, which brings the ability to generate sounds that vary more freely depending on how the keys have been struck, in addition to allow a more realistic implementation of the distinctive resonances and acoustical noises of real pianos.
The long scale necks on Leo Fender's basses—with a scale length (distance between nut and bridge) of 34 inches (864 mm) — set the standard for electric basses, although 30-inch (762 mm) "short scale" instruments, such as the Höfner 500/1 "violin bass" played by Paul McCartney, and the Fender Mustang Bass are also common. Short scale instruments use the same E-A-D-G tuning as a regular long scale instrument. Short scale instruments are good choices for bassists with smaller hands, such as children or young teens who are just starting the instrument. While 35-inch (889 mm), 35 1⁄2-inch (902 mm), and 36-inch (914 mm) scale lengths were once only available in "boutique" instruments, in the 2000s (decade), many manufacturers began offering these "extra long" scale lengths. This extra long scale provides a higher string tension, which may yield a more defined, deep tone on the low "B" string of five- and six-stringed instruments (or detuned four-string basses).
These keyboards are perfect for any student, child to elder, who is interested in learning how to play piano. They are inexpensive, have built-in speakers so an extra amplifier isn’t necessary, and include multiple piano sounds and simulated acoustic-piano action (aka “key feel”). These keyboards are relatively light—all our picks weigh around 26 pounds—so it’s possible for one person to carry the piano when necessary.
During the 1990s, as five-string basses became more widely available and more affordable, an increasing number of bassists in genres ranging from metal to gospel began using five-string instruments for added lower range—a low "B" string. As well, onboard battery-powered electronics such as preamplifiers and equalizer circuits, which were previously only available on expensive "boutique" instruments, became increasingly available on mid-priced basses. From 2000 to the 2010s, some bass manufacturers included digital modelling circuits inside the instrument on more costly instruments to recreate tones and sounds from many models of basses (e.g., Line 6's Variax bass). A modelling bass can digitally emulate the tone and sound of many famous basses, ranging from a vintage Fender Precision to a Rickenbacker. However, as with the electric guitar, traditional "passive" bass designs, which include only pickups, tone and volume knobs (without a preamp or other electronics) remained popular. Reissued versions of vintage instruments such as the Fender Precision Bass and Fender Jazz Bass remained popular amongst new instrument buyers up to the 2010s. In 2011, a 60th Anniversary P-bass was introduced by Fender, along with the re-introduction of the short-scale Fender Jaguar Bass.
Maybe you're looking for something a bit more conspicuous, that you can make into the centerpiece of your music room? If so, you'll want to investigate options like the Yamaha Arius YDP-142 and Suzuki Micro Grand Digital Piano. These advanced instruments sound every bit as gorgeous as they look, and they offer the ability to record your and store your performances to listen again later or even to playback as accompaniments.
