• 100% analog Mix, Tone and Level controls for warm, organic sounds.
• Mix control ranges from 100% dry to 100% wet.
• Speed and Depth work in conjunction to control their respective functions 
of the modulation.
• Detune alters the choral voicing up or down, giving you a chorus sound without

modulation when Speed and Depth are set at minimum.
• Multi Voice adds dimension and thickens the sound with additional 
choral voicings.
• Buffered bypass eliminates the shortcomings associated with "true bypass"

(pops and clicks, and high-end loss when multiple pedals are connected together),

as well as signal loss associated with other types of switching circuits.
• Custom, silent-switching actuator.
• Heavy duty, all metal construction.
• Operable with 9V alkaline battery (not included) or optional DC power supply

(Tech 21 Model #DC4-A).The evolution of the chorus effect seems to have gotten

stuck in '80s pop, along with over-processed guitars, cheesy synths and popped collars.

This ain't that kind of chorus. When we designed the Boost Chorus pedals we went back

to the '70s, when choruses were rich, smooth and manly. We figured out what made these

vintage stompboxes sound so good and poured that knowledge into a new kind of chorus

pedal with greatly improved performance and a whole slew of never-before-heard sounds.

Slapback, echo, flanging and doubling effects are all possible from the modestly named Boost

Chorus pedals.Because of the way traditional chorus pedals typically interact with their amps,

most bass players would rather put an angry badger on their pedalboard. The Bass Boost

Chorus avoids seasick tones, and badgers, through a specially-tailored design. It features a Detune

control to adjust the pitch of the choral voices, adding sonic girth to create thick, lush, bass-perfect

chorus. Speed and Depth controls add modulation, so at minimum your fundamental notes are

preserved. Finally, a chorus that works in harmony with your bass.

Sample settings include such styles as Cure Bass, Hooky, Squire Harmonized, Bass Chorus-no

modulation, Jaco Fretless, Vibrato Bass, Triple Voice Bass, Infinite Flange, Bass Thickener, Subtle,

Shimmer for Guitar, Randy Rhodes for Guitar.
