+1 on the fishman pro platinum. I don't know about the Microbass, but in my experience the Fishman has been great. In addition to improving the tone of the pickup on my bass (Realist) even when I keep the EQ flat, the feedback phase shifter has been a godsend when trying to fight feedback. Also, unlike other gizmos with batteries I've tried, the Fishman will warn you about 4 hours in advance before the batteries die, so I think its pretty cool
