each clip may
have the clean bass sound first, then the effect only,

just the chosen effect first, then the effect blensed with
sound through the ParaLooper.
The ParaLooper is something every effects-using Bass player should have, because it will 'Bassify' any bottom sucking, high-passing guitar pedal out there. And, it's pretty simple to build, too. Instead of just an effect loop pedal, this is actually a little mixer that blends your straight signal with whatever effect (or chain of effects) you plug into the send & return jacks. There are controls for wet/dry balance and overal output level (boost & cut).
Experimenting with parallel effects chains a snap, in mono or stereo. For example, you can plug whatever effect(s) you have connected to the send into a second amplifier or mixer/recorder channel. It can also be used just like a two-channel mixer itself by plugging a second source into the return jack. There is also a low-pass filter (capacitor to ground) on the clean signal that can be switched in for even more low end.
The basis for the ParaLooper is the Bass-Thru, from a Japanese web site that happens to have some other interesting schematics, too.
Here's a PCB layout that I did:
