I'm looking for something to add more girth.... bigness to my sound as a boost to kick in on choruses, or big moments in a song. I'm not looking for OD or distortion. Something that creates instant fatness, fullness, and "boom" without sucking the life out of my tone. Not a synthy dubby type pedal like the Meatbox. I was thinking maybe the Xotic RC Booster or Fultone Fatboost with Bass knob turned up a fair amount? Any other recommendations?
I always suggest either the Southampton Fifth Gear or the DOD fx10. Both excel greatly in the areas you want. Two of the best if not THE best boost pedals I've tried. The fx10 especially can warm up and get super fat and it still seems to keep it's articulation and attack. It's really weird how it does it but it does do it.
