Constant Memory
As you adjust an effect (say, a Screamer distortion running in effect memory A of FX 
Unit 1), those adjustments are retained as you switch away to a different A/B/C memory 
and back again—no save function is required. It’s just as if you were adjusting different 
physical stompboxes, each of which would still have the last knob settings you made to 
it. The same is true as you switch scenes, swapping one virtual pedalboard for another: 
when you come back to a previously used scene, it loads with all the last adjustments you 
made to it, just like a real pedalboard of physical stompboxes would. 
If you prefer that scenes not remember your last adjustments, hold the LOOPER 
CONTROLS footswitch to activate SETUP mode, then set the Scenes parameter 
to MNLSAVE (Manual Save) instead of AUTOSAVE. You will then need to use the 
scene setup mode any time you want to manually force a “save” of current settings to a 
scene: hold SCENES, step on the switch for the current scene, then step and hold on 
that same switch again to complete the “save” (display will say Copy Completed). 
Tap Tempo
Tap tempo is available for all Delay effects, most Mod effects, and some Filter effects 
(details at www.line6.com/manuals). For these effects, turn the second top row knob 
of the FX Unit all the way to max, and you’ll switch between tap tempo and regular con-
trol modes. Once you’re in tap tempo control mode, turn the knob to select one of the 
available note values. Tap 2 or more times on the TAP switch, and all the effects set to 
tap tempo control will change their time/speed/tempo to match the tempo you tapped. 
To end tap tempo operation for an effect, turn the knob to max again. 
Note: Parameters set to tap tempo control are NOT affected by expression pedal 
operation. 
Mono/Stereo
Some Models (like Stereo Delay) provide stereo operation. When run before a mono 
model (like a distortion), the signal will collapse to mono as it feeds the mono 
effect, and will then be passed on in mono to the next effect or outputs.
