Electroharmonix SwitchBlade: I use it as an input switch; that's
  why it's upside-down. Switch between two guitars or guitar & bass

TC-Electronic Tuner

Digitech Drop: Downtune in half-steps. Extremely good tracking. Way 
  better than the Morpheus. E-Standard can go down to A-Standard;
  drop-D can go down to drop-G. Loses some tone the lower you go

Electroharmonix MicroPOG: Octave down + Octave up + dry signal. I
  mainly use octave down with a little dry signal blended in

Dusky Mandorla: "Classic Treble Boost". Gives that extra bite for
  leads or even meaner rhythms. Great in combo with the Drop to
  make up the lost tone

Electroharmonix Sentinel: Noise Gate. I forego the send/receive
  loop because it adds noticeable latency. Works well straight-
  through

Boss OD-2 Turbo Overdrive: Fantastic, strong overdrive in Turbo
  mode. Retains articulation of notes. Turbo off is good for nice
  saturation and boosting fuzz/distortion down the line

Boss BF-2 Flanger: I love flangers. Rarely hear them in other 
  people's recordings. Most guitarists love the phaser but the
  flanger is very underrated

Boss CH-2 Chorus: just a chorus

Dunlop Crybaby: good wah-pedal. Every wah is noticeably different.
  This is just the one I went with. I like that the switch is under
  the pedal rather than beside it, as with the Morley

Keeley Compressor Pro: Fantastic compressor. All the necessary knobs

Gamechanger Audio PLASMA: cool concept of a pedal. Read how it works
  on their website. It's a wild distortion. Gotta be careful with the
  voltage (gain) -- it reaches white noise/static territory

Gamechanger Audio LIGHT: moar cool, but reverb. I haven't played around
  with this yet. Lots of controls, almost too much variety of 'verb

TC-Electronic Mimiq: doubles the signal with slight variations on pitch,
  timing, and tone (I think). It can create 1, 2, or 3 "doubles" but I 
  only use 1 to avoid that chorus effect. Creates a great stereo effect
  both live and recording

TC-Electronic Quintessence: add harmonies. Again, great in stereo; splits
  the dry signal from the harmony between two amps or L/R on a stereo 
  channel strip

TC-Electronic Flashback: I specifically bought this for the Ping-Pong
  mode. For some reason this mode was removed in v2. So I paid less to
  get more by buying v1

Saturnworks Stereo Looper: simultaneously switch on/off two effects loops.
  I use it to trigger two different fuzz pedals (one for left, one for right)

Dusky Hypatia: good-range fuzz. retains articulation. not overly fuzzy, i.e.
  not static

FuzzHugger Doom Bloom: haven't really played around with this too much, but
  it sounds good

ADA GC-6 Speaker Simulator: decent-sounding speaker sim when going direct 
  to a mixer. Sounds much crappier than Guitar Rig 4 so I don't record with it

Digitech JamMan Stereo: stereo looper
