i posted a thread about essential CCM pedals a while ago.. i've been messing around with A TON of pedals, from exotics to ordinary run of the mill boss's
and i'll be honest. you really don't NEED any pedals.
granted, some songs call for a bit of an overdriven sound or some aura-like echo, i have yet to encounter situations where i'd use a pedal for more than one songs a set (if any)
However, some would be definitely nice to have (in order of importance & suggestion):
Compressor (Demeter or EBS)
Analog Delay (Deluxe Memory Man or Carbon Copy)
Overdrive (Truly Beautiful Disaster or Valvedrive)
Volume Pedal (ErnieBall or Boss) and/or
Clean Boost (MXR or BBE)
Chorus/Flanger (stereo mistress or tc)
----------------------------
[[seriously.. do u need these for praise? not really, but they're so much fun!!!]]
Envelope/funkifresh (Q-tron+ or Moogerfooger)
Synth (Akai Deep Impact or Moogerfooger)
miscellany would be probably loop pedals or isp decimators/noise gates but these are total luxuries or for the electronically anal-retentive imo.
Pretty important are DI boxes. Not too familiar with them, as i don't use any myself, but u could look into the Sansamp PBDDI (the dirt [and the di] on it is pretty impressive from what i hear on these boards)
