Okay, here's what I use:
I used to have a lot more pedals but I've really streamlined it down lately to the ones I find most important.
On the left there's a DD-3, I mainly use this as a short slap back delay to give solos an extra bit of atmosphere. My amp doesnt have reverb so it can be useful to simulate that. Sometimes I might screw around with 'echo song'-type effects when I'm at home, that can be fun. I havent been interested in delay models higher than the DD-3, but then I guess people who are really into their effects or want an extremely long delay might not find this to be enough for them.
Next, a GE-7 - this gets no use at home but it is probably the most important pedal I use live because it makes my solos jump out when they need to. As you can see from the sliders, I just keep them all the same but then have the gain slider up a little so I'm louder when it's on. I've tried fiddling around with the frequencies, but I'm pretty happy with the tone I get from my amp on it's own so I havent really felt the need to dial in an alternate 'solo tone'.
In the middle, an MXR 'Smart Gate', probably the second most important on my board! My amp on the gain channel is NOISY. I get hiss, hum, buzz, squeals, everything. Stick this in the effects loop though, and it's dead silent when I want it to be. It also stays open for sustained notes and shuts quick for staccato stuff. A clever device indeed!
Those last three go through the effects loop of the amp since theyre not very effective in the front.
Next, my absolute favourite! An RMC Teese Wizard Wah. I've owned a few wah pedals before, including a Crybaby From Hell, and this one beats them all in terms of tone. You know when a wah makes you want to mimic the sounds with your mouth? This does that! The sweep range is enormous, but it manages to stay rich on both the heel down and toe down positions.
Finally, a TU-2. Understated brilliance. Quite simply, my guitar would be out of tune half way through most sets without it!
