1 One way to handle this is to have your lead FX in one path (maybe top) and the other FX in the other (maybe bottom) path. Some will be shared and can go in the main path. Then set up the pedal to pan between full lead, rhythm, or a mix. This works exceptionally well other than a few downsides:
- Some FX you won't be able to get in the exact order due to how the paths relate
- You won't be able to use the pedal for some other things, although with the toe button you can still switch on things like WAH
- You may run out of FX or DSP space which I sometimes do but this is not too common
2. The other way to do this which takes more work but can make the patch better in the end is to look at each setting you want to change in your lead, and assign it to the pedal. For instance, if for lead you want the amp gain moved from 30 to 50, the volume moved from 80 to 100, the delay mix from 30 to 50, etc...you can assign all of these exact numbers to the pedal. Then like the first way you can push up for lead, back for rhythm, or anything in between.
And the reason the "anything in between" parts of the above 2 options can be important is depending on the room, song, mood of the band, etc...I rarely find a single button is what I want all the time. Very often I just want to go some of the way, and using these methods make that possible.
