I only use two things for effects. It depends on if I am taking an amp to a gig or not. If I am, I take a Digitech RP100, mostly for a little compression (I then kick the thing under the amp since it's on a stand). If I don't take an amp, I use Amplitube 3 with my laptop and just plug into the PA. I already have presets that I like, and just scroll to them to play them.

I have been toying with the idea of adding a wah, and I have been perusing Ebay checking out the triple tube modded ADA MP-1's... I mean, I do still have an Alesis Multiverb in the garage, and a 31 band eq... :P
