Interesting indeed...
I like how my Blackstar ID-core 100 sounds (direct out) on a recording. Its a very good studio amp, but leaves a lot to be desired live.
When i play my pair of DSL40C's live, i notice how great the tone is, how quiet my rig is and how the amp responds to pick attack.
The DSL40C - for me - is just so versatile, lightweight and fits in the trunk of my daily driver Mustang.
I have played through many, better, more expensive rigs, but mine is always quieter and has that little edge that i find missing.
Our sound guy friend (Kurt) commented yesterday on how quiet my rig was and how clean it sounded until i really dug into it.
I guess the DSL40C just works and i have no need of anything better...
