If you can't make effective use of the filters in the EB, then either you need a better understanding of filters and frequency or you are just trying to warp the f*ck out of stuff and should be using a Sherman since that's one of the best Filters for just mangling a sound.
The EB can do LP, BP, HP or Notch pretty easily, resonance is a bit tricky.
I can get better results with the EB, than with the Electrix Filter Factory.
The MFC tends to work better than the Electrix in many cases, so it can be a good choice.
The problem with the EB really comes down to Akai doesn't always design things from a normal mentality so it's a little odd at a glance.
Combine that with the routing and not being able to sample though or re-sample through effects and it can box you in.
