Aphex compresser - I originally bought this as a battery powered pre-amp as I used to go through a battery powered PA doing gigs on a train (I'm not joking! Not recommended though, as you keep having to get out of the way of the conductor - the train conductor, not a musical conductor). I just use a touch of compression - the rest of the band seem to like it!
Aphex bass exciter - great pedal - I keep the tone controls on my Mark Bass amp flat and use the pedal for EQ. Then I can use the amp controls for any dodgy acoustics in the room, and use the bass controls only during a gig for easy tone variations
Boss Bass Chorus - for those slower fretless moments - not used much at the moment
Boss tuner pedal - essential kit - tune up silently in seconds while the lead singer is adjusting his make-up. I also use it as a mute pedal
Overall, though, I go through phases - sometimes I go for effects, sometimes I don't. The tuner is well worth having though
