ATM I'm using a bad monkey to get a boost for bluesy solos over my crunch channel.
I use it to get a little extra gain and make the soft lead channel "softer".
I like the pedal but still I want something better.
What I want is:

1. A boost for blues solos when activated over my crunch channel (really light distortion)
2. A little more gain in the 3rd channel (to make it smoother)
3. A boost for metal/hi gain solos in the 4th channel (hi-gain lead) to make it smoother.

So, basically, I want a tubescreamer type pedal.

Recommend me some good pedals that can do what I want and tell me if it's really worth replacing the bad monkey.
