Just to make things a bit more complicated, you should keep the PBDDI in mind as well. It costs new and used about the same as the BDDI. Sure it's a big pedal, but useful if thats your thing. If you have figured out that you can have your mids by setting the bass and treble accordingly, then it is nice to have some presets a click away.
But, as said earlier, you really need to go listen to them in order to get a feel for what they do for your sound.
Don't run, we are your friends.
