User Manual

1. Passive & Active Input - Start by using the

passive input. If your bass’s output distorts the input

section, switch to the active input. You are clipping

the input when the TUNER/CLIP (see 11) button

lights up. (A “passive” instrument has no built-in

preamp and does not use a battery. Active Input - An

“active” bass utilizes a battery operated preamp.)

2. Amp Models - Spin this knob to select one of

5 groovealicious Amp Models or Synth Bass. All the

LowDown controls will automatically dial in to sound

great with that Amp Model, so you can just play!

3. Drive - Like the volume or gain knob on other

amps; controls how much “dirt” you get in your sound.

4. Tone Controls – Bass, Low Mid, Hi Mid and

Treble controls are customized for each Amp Model

to give you optimal tonal control.

5. Channel Volume - Without affecting your tone,

this control helps you balance the volumes of different

amp-and-effect setups that you store in your LowDown’s

channel memories (see 10). Start with it at 2 o’clock

then adjust the Drive and Tone Controls to get the

sound you want, and then use Channel Volume to

make your presets even in volume.

6. Opto Comp - Turn clockwise to even out your

playing dynamics (more compression). Watch for the

Threshold light, and set the knob so that it comes on

just at the point where you play with your typical

intensity.

7. Smart FX - Spin this knob to get great FX, fast

and easy: This knob selects Envelope Filter, Octaver,

or Chorus, with a range of settings – from subtle to

overpowering – for each effect. The LED shows the

active effect.
