Experience the versatility of thick to transparent chorusing and everything in between. There are 2 output choices OUTA is more organic sounding, while OUTB is mildly brighter sounding. Use either output for mono, or both for a complimentary beautiful lush stereo sound. The Width control dials in a variety of chorus sounds from spacious 3D sounds, to compressed thickening chorus. Crank up the Depth to get deep chorus or pitch bending Vibrato, or increase the Rate for a hint of Rotary Speaker swirl. The Blend pot mixes in as much analog instrument with lush Chorus Waves as desired. Although a transformer is included, a worry free 9VDC input can accept and polarity from a pedal board supply! Smaller can be better - measuring at only 5L x 4W x 2.5H. This effect is true bypass, constructed using a heavy steel enclosure, steel switches, and steel pots to withstand every road environment. DLS products are all custom crafted in the USA!
