I like phaser a lot more than chorus on bass, but without a clean blend, it's like "Wow, the bass is really strong...wait, where did it go? Oh wait, it's back again...oops, now it's gone again," over and over. So I opted for chorus instead. Tried a lot of them and went with the Bass Chorus Deluxe. MXR's Analog Chorus is also really sweet, but I thought I could use the BCD's flanger as well (I can) and the crossover circuit that cuts the effect on the lowest frequencies so you don't get the bass washout (nice feature but I ended up thinking it didn't need it...now put it on a Phase 90 and I'd be all over it).
