For what it's worth.
I use a Lexicon MPX1 rack mount multi-effects controlled by a Yamaha midi controller pedal board.
I have five basic patches that I have set up, and each has its own foot switch. The differences between the five are that two are flanges and three are choruses.
There is another foot switch that turns the flange/chorus on or off for any of the patches.
There is another switch that chooses between two different reverb settings for all five patches. I always have one or the other of the reverbs on all the time.
There is another switch that turns delay on or off for all patches.
And one that turns vibrato on or off for all patches.
The board also has a pedal that I've patched as a volume pedal.
Personally, it think all sounds pretty good. The tune I linked to a few weeks ago had reverb, chorus, delay, and vibrato, all of which was a bit too much. If I record that tune again, it probably won't have the vibrato.
The system was very difficult for me to set up; and now that it's working I hesitate to make any changes.
I may at some point patch in another pedal to control the delay speed, and maybe one to control the amount of delay as well. Etc.
Of course, as mentioned above, it depends on what you are playing. And I'm not playing metal, or even rock. All of the stuff I'm working on right now is solo oriented where I'm doing a lot of chordal things and playing way up on the neck. And it's a steep learning curve; I still can't play any of the songs consistently well enough to take them out in public. And there's still not enough material to do a two hour set. I have a lot of work to do. But I think it sounds pretty good, and should work well for a solo coffee house gig ... some day.
