Chaining amps into each other?

I'm a fan of using the Soldono (SoloC from LePou) as a boost on certain things. It really brings out the "stringy" sound and can help with note articulation.

Exactly, a great example is when I receive dark, muddy guitar DIs cause the band was bored to change strings ^^

I use the clean mode with no distortion at all but just the Treble knob at maximum. I emulate the sound of a new string that way.
 
If you mean the tracks they're both free to download, just press the arrow on the soundcloud player:
