Something I just thought of yesterday, watching a few pedal reviews. Bassists have to be careful with pedal effects, because you don't want to mess with your fundamental bass frequencies too much. Full-range distortion changes your mix to emphasize treble, other overdrives can chop off the low end completely (expecting a guitar that the pedal then shoehorns into the full mix), and pitch modulation (chorus/vibrato), even at very subtle settings, can push you out of tune.
The usual fix for the "bass version" of an effect is either a dry blend or, for effects like chorus where the effect is already a wet-dry mix, an HPF feeding the effect with a full-range dry signal. This allows you to bring back some low end, or keep the effect from messing with your lowest frequencies in the first place.
So, here's the idea; why not put those controls into a loop pedal? Put the effect(s) you like the character of, but don't like the effect on the low end, into the loop of this pedal. Now in addition to the new pedal being a loop switcher controlling the basic on-off of the looped effects, you can either blend some dry signal back in, or HPF the signal sent to the loop, or both. Now any pedal can be a "bass" pedal, imparting its color to your tone while giving you the tools to keep the root pure. Throw in a buffer/TB switch for the pedal's own switching and I bet you'd have an audience.
