Various electronic bass effects such as preamplifiers, "stomp box"-style pedals and signal processors and the configuration of the amplifier and speaker can be used to alter the basic sound of the instrument. In the 1990s and early 2000s (decade), signal processors such as equalizers, overdrive devices (sometimes referred to as "fuzz bass"), and compressors or limiters became increasingly popular. Modulation effects like chorus, flanging, phase shifting, and time effects such as delay and looping are less commonly used with bass than with electric guitar, but they are used in some styles of music.
The bare minimum requirements for a budget digital piano are to have 88 keys (the same number found on traditional acoustic pianos) and internal speakers to facilitate practicing without an amplifier. Beyond that, some amount of weighted key action (either semi-weighted or hammer action, more on this in a moment) and an accurate piano sound were the primary deciding factors for our picks. An included stand and sustain pedal were not requirements, as aftermarket options are readily available and inexpensive. (We discuss some options below.)
Some drummers arrive at the venue with their drum kit and use the mics and mic stands provided by the venue's sound engineer. Other drummers bring their all of their own mics, or selected mics (e.g., a good quality bass drum mic and a good mic for the snare) to ensure that they have good quality mics for each show. In bars and nightclubs, the microphones supplied by the venue can sometimes be in substandard condition, due to the heavy use they experience.
The number of frets installed on a bass guitar neck may vary. The original Fender basses had 20 frets, and most bass guitars have between 20 and 24 frets or fret positions. Instruments with between 24 and 36 frets (2 and 3 octaves) also exist. Instruments with more frets are used by bassists who play bass solos, as more frets gives them additional upper range notes. When a bass has a large number of frets, such as a 36 fret instrument, the bass may have a deeper "cutaway" to enable the performer to reach the higher pitches. Like electric guitars, fretted basses typically have markers on the fingerboard and on the side of the neck to assist the player in determining where notes and important harmonic points are. The markers indicate the 3rd, 5th, 7th, 9th fret and 12th fret (the 12th fret being the octave of the open string) and on the octave-up equivalents of the 3rd fret and as many additional positions as an instrument has frets for. Typically, one marker is on the 3rd, 5th, 7th and 9th fret positions and two markers on the 12th fret.
