Re: To keep a pedal or no?
Depends... barring the obvious "dump the stomps that truly suck" prerequisite:
If you've got a studio/session player thing going on, keep them. You never know when you might want to grab that "different" pedal for a different effect.
If you have your tonal palette sussed out, keep them.
If you don't really have your tonal palette sussed out yet, it's probably best to trim the fat.
That said, a few years ago I removed all of my distortions, ODs and AIAB (amp in a box) stomps; I wanted the amp to do the heavy lifting so to speak. (I will however re-acquire the MXR Distortion+ because it was an ubiquitous stomp and also it works best as a "gooser" and not a true distortion).
