Pelhams gate story just made me think cause I have really high gain dirt and it makes my humbucker equipped basses howl, so the bass vi probably will make some darling screams, but I don't just play the heavy. Also I only have one 9v spot left on my board so It'll probably wind up being something practical like a gate or hpf. I feel weird adding anything other than practical boxes so I don't disturb the dano lineage with riff raff.
That said I really would like a fuzz/trem/reverb, but I'd only use them with guitar or the bass vi so I'll probably just find an old peavey head or something cheap to cover those when I care, and I keep the Dano bloodline strong and incestuous.
Sartori I have a kill switch on my bass, it's handy for mutes if your not using time based effects then it causes rhythmic glitching, after your last pedal would be the most effective for a full stop of sound mid song I'd think.
