DLS has once again designed one of the 

warmest 

chorus effects in the industry!  The 

Ultra Chorus

II

 

is two chorus units in one.   

The musician can preset both chorus channels and switch between the two on the fly!   A Blend control allows the musician to 
mix as much analog instrument with our wonderful chorusing sound.  As with all DLS Effects, the analog instrument always stays 
analog!  Choose from any hookup option (

Mono in-Mono Out, or Mono in-Stereo Out, or  Stereo in-Stereo Out

).  Internal trim pots 

allow the musician to dial in levels of InputA-OutputA, InputB-OutputB, and Chorus Regeneration (Regen) to taste.      

The 

Ultra Chorus

II

 is truly one of the sweetest sounding and most powerful chorus effects on the market today.  It’s quiet, 

pristine, versatile, and allows the musician to dial in the sound they are after.  DLS effects are extremely well constructed using a 
heavy steel enclosure, steel switches, steel pots, and a beautiful powder coating to withstand every road environment.
