I have a Soulbender.
At first I didn't understand it. In fact I wanted to sell it. Then I reallized it wants to be played into an amp that isn't bright like a Fender, rather a well rounded amp like a Marshall. Now it is my holy grail sound. I would instantly buy two backups if it got stolen.
Also I prefer it with the guitar volume backed off one or two points.
There's a clip using just a soulbender into a Marshall non master volume amp (excuse the playing). A Fender Strat was used.
I have since developed a great EJ sound by running the Soulbender into a DS-1 then into the Marshall stack. The DS-1 distortion is set to minimum.
