Bass guitars require a bass amp. It is possible to play a guitar through a bass amp, but you cannot play a bass through a guitar amp without damaging the amp. Amplifying low-frequency sounds is more challenging and requires both different equipment and more space compared to an ordinary guitar's amplification needs. Like guitar amps, bass amps can be combined or separated into the head and the speaker.
Three sounds (Grand Piano Concert, Grand Piano Modern, and Elec. Piano 1) have dedicated buttons on the control panel. Selecting any of the other 15 sounds requires the player to press the Function button and a corresponding piano key labeled with the name of the sound, such as Vibraphone or Jazz Organ. The keys used for instrument selection are in the middle of the keyboard, starting at middle C, for easy accessibility. Some other keyboards that use this selection method have the selection keys assigned to the bottom octave of the keyboard, which can make changing sounds a bit more difficult because you have to look and reach down to the far left end of the keyboard. If you have a library of sounds on your computer, the Casio Privia PX-160 can be used as a controller by connecting it to your computer via USB.
There's a lot to be said for tradition when it comes to the bass guitar, and it's a tradition that ultimately goes back to the originals: the Jazz Bass and Precision Bass. With some stellar options available from Fender and Squier, you're in a good place to get started with those iconic bass guitars. On the other hand, if you'd prefer something a bit more unique, you've got no shortage of options. Over the years, the bass guitar market has grown hugely, and there are now a ton of choices ranging from beginner-friendly instruments like Rogue and Dean models all the way to professional masterpieces from luthiers such as Warwick, Schecter and Rickenbacker.
All cymbals other than rides, hi-hats and crashes/splashes are usually called effects cymbals when used in a drum kit, though this is a non-classical or colloquial designation that has become a standardized label. Most extended kits include one or more splash cymbals and at least one china cymbal. Major cymbal makers produce cymbal extension packs consisting of one splash and one china, or more rarely a second crash, a splash and a china, to match some of their starter packs of ride, crash and hi-hats. However any combination of options can be found in the marketplace.
Traditional digital pianos vaguely resemble an electronic organ or a spinet harpsichord but usually lacking a fully enclosed lower section, while some models are based on the casework of traditional upright pianos with a fully enclosed bottom part and pedals that look like actual piano pedals. An opposite and recent trend is to produce an instrument which has a unique and distinctive appearance, unobtainable with a conventional instrument. Yamaha , Kawai and Casio makes a model which is designed to stand against a wall and is far shallower from keyboard to back than any possible upright design, as well as shorter height.
A well-known bass humbucker is the pickup used on the Music Man series of basses; it has two coils, each with four large polepieces. This style is known as the "MM" pickup for this reason, and many aftermarket pickup manufacturers (companies that make and sell pickups that you can custom-add to your bass) and custom bass builders incorporate these pickups in their designs. The most common configurations are a single pickup at the bridge, two pickups similar in placement to a Jazz Bass, or an MM pickup at the bridge with a single-coil pickup (often a "J") at the neck. These pickups can often be "tapped", meaning one of the two coils can be essentially turned off, giving a sound similar to a single-coil pickup.
Another design consideration for the bass is whether to use frets on the fingerboard. On a fretted bass, the metal frets divide the fingerboard into semitone divisions (as on an electric guitar or acoustic guitar). Fretless basses have a distinct sound, because the absence of frets means that the string must be pressed down directly onto the wood of the fingerboard with the fingers, as with the double bass. The string buzzes against the wood and is somewhat muted because the sounding portion of the string is in direct contact with the flesh of the player's finger. The fretless bass lets players use expressive approaches such as glissando (sliding up or down in pitch, with all of the pitches in between sounding), and vibrato (in which the player rocks a finger that is stopping a string to oscillate the pitch slightly). Fretless players can also play microtones, or temperaments other than equal temperament, such as just intonation.
Just like the acoustic instruments they're derived from, digital pianos come in different sizes. They also offer dozens of options for your perusal, so you can weigh all kinds of factors to find the right model for you. For instance, if you're looking to pack a lot of piano into as small a space as possible, consider instruments such as the Williams Allegro 88-Key Digital Piano or the Casio CDP-120. These are fairly compact pianos, but that doesn't limit the breadth of their samples and sound settings.
