CONGRATULATIONS
on your purchase of The Sweeper, our classic chorus pedal for the bass
guitar.
The Sweeper is a premium-quality chorus pedal custom engineered
for the BASS ONLY. This means that no matter what rate or depth you
set, you’ll get a phenomenal-sounding chorus effect – in stereo. The
Sweeper is intuitively designed and easy to use. Just turn the page to
get started.

BACK TO BASSICS
The Sweeper has everything you need to get the full range of classic
bass chorus sounds – using just a few simple controls.
DEPTH controls the amount of chorus effect. Turn it down for a subtle
chorus, crank it up for that great full sweep.
Use the R ATE control to set the speed of your sweep. A fast rate combined with a low depth level gives you a light shimmering sound, while
the slower rate and higher depth creates a dramatic chorus effect.
VOLUME controls the overall output of The Sweeper, and the INPUT
LEVEL on the side of the unit helps you avoid overdrive distortion by
turning down the input signal. If the red overload light comes on, the
input level is too high.
Note: If you’re in the studio or have a stereo live setup, try using The
Sweeper’s stereo outputs for a truly mind-blowing stereo chorus!
