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.
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.

First and foremost, it's hard to go wrong with the classics. Fender can definitely take the credit for making the bass guitar the instrument it is today, and with a Precision Bass or Jazz Bass from Fender or Squier, you can experience the sound and feel that laid the groundwork for all others. Of course, what those others have done with the bass guitar is nothing short of amazing, and you'll also find plenty of artisan axes here from the likes of Schecter, Rickenbacker, Warwick and more. The bottom line is choice: there's a bass to satisfy any player.
Several colleges offer electric bass training in the US. The Bass Institute of Technology (BIT) in Los Angeles was founded in 1978, as part of the Musician's Institute. Chuck Rainey (electric bassist for Aretha Franklin and Marvin Gaye) was BIT's first director. BIT was one of the earliest professional training program for electric bassists. The program teaches a range of modern styles, including funk, rock, jazz, Latin, and R&B.
Specific bass brands/models became identified with particular styles of music, such as the Rickenbacker 4001 series, which became identified with progressive rock bassists like Chris Squire of Yes, and Geddy Lee of Rush, while the StingRay was used by funk/disco players such Louis Johnson of the funk band The Brothers Johnson and Bernard Edwards of Chic. The 4001 stereo bass was introduced in the late 1960s; it can be heard on the Beatles' "I Am The Walrus." 
A drum kit — also called a drum set, trap set (a term using a contraction of the word, “contraption”), or simply drums — is a collection of drums and other percussion instruments, typically cymbals, which are set up on stands to be played by a single player, with drumsticks held in both hands, and the feet operating pedals that control the hi-hat cymbal and the beater for the bass drum. A drum kit consists of a mix of drums (categorized classically as membranophones, Hornbostel-Sachs high-level classification 2) and idiophones – most significantly cymbals, but can also include the woodblock and cowbell (classified as Hornbostel-Sachs high-level classification 1). In the 2000s, some kits also include electronic instruments (Hornbostel-Sachs classification 53). Also, both hybrid (mixing acoustic instruments and electronic drums) and entirely electronic kits are used.
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.
