I just made some changes to the pedalboard I use for gigs, now consisting of, in this order:
Korg DT10 tuner
Diamond Compressor
Catalinbread Hyper Pak "dirty channel" (usually considered a low gain overdrive, in a very small package)
MXR Carbon Copy analog delay
Catalinbread Semaphore tremelo (4 knobs, 2 switches, for more control than you probably need, but it sounds good and isn't as expensive as some of the other better sounding trems)
I'm probably going to switch over to George L's cables with right angle connectors so I can reclaim some board space and add one more pedal, which is a Barge Concepts FB-X Feedback/Looper pedal. Then I will put everything after the compressor into the loop and control the dry/loop mix with an expression pedal.
I'm not a heavy delay user by any means, but I really like a nice analog modulation delay and the Carbon Copy is good for the money and is compact. The expression pedal will allow me to pull the delay out for the beginning and ends of phrases without a sudden cutoff or having to hit a switch at the right moment; the actual blend is more abrupt than I would like, it's not a perfect system, but it works well enough to be much better for me than hitting the delay switch all the time.
I took off most of the knobs so they won't move during transit (I use an SKB board that goes into a cordura bag and I have often had issues with knobs moving which I didn't notice until it was too late). I have a Voodoo Lab Pedal Power 2 power supply, which takes up a bunch of space on the board, but seems to be high quality (not noisy thanks to the toroidal transformer) and allowed me to ditch the wall wart I had been using. I really hate wall warts especially at gigs when I have to set up quickly and never know how many outlets will be available, how far away they will be from where I will be standing, and sometimes have requests from my slacker bandmates to use slots on my power strip, where the wall wart takes up a lot of space.
