They seem pretty bright to me. A good tool for brightness/darkness is adjusting the definition. Turn it up just a touch for darker sounding profiles and down for bright sounding ones. I found Mbritt profiles to be comparatively a tad darker than Tone Junkie. So which is better? Depend on your own taste, guitar, pickups, which pickup position you primarily are trying to use, style, strings, pick, personal technique and playing style, monitoring device, style of music, tone in a mix vs tone by itself.
The best part of this adjustment is no need to use up an effects slot. I usually start here before touching the tone stack as well.
I also think of it as a pickup translator. In that, if a profile was crafted with the bridge pup being primary, rolling up the definition will make it more balanced when using the neck pickup, and the converse is true as well.
