Some others to consider, depending on whether you can get them easily or snag them on reverb for a decent price.
Wren & Cuff have a few pedals worth checking. The Phat Phuk B is killer, and the Super Phat Phuk is an expanded version of that, although not identical. If you want more gain on tap, try the Pickle Pie Hella Fuzz. The clean blend on it is great, and you can run it mostly clean with lower gain for a very nice dirty-not-distorted sound.
Oh yeah - TC Electronic Spark Booster! The full sized 4-knob version is great. Should be easily available for pretty cheap. It has fat, clean, and mid modes, which all work well on bass. The gain is natural sounding and will just give you some bite.
