Which octaver is good with bass?

[JebemMajke]

I play bass in my band ( i have more solos than "lead" guitar player ) and im looking for something to color them a bit. So i want to make and octaver but i m not sure which one will not turn my bass into a mid loaded monster. I dont want it to lose any of the existing bass. So RM Octavia, Ampeg Scrambler or fOXX Tone Machine? I like how scrambler sounds on guitar http://www.youtube.com/watch?v=XfzP7ubrYlM great, and is kinda cool sounding here http://www.youtube.com/watch?v=vaw1-xBm3i4, but i think it loses some bass and im not sure how it would fit in our stoner/punk/rnr/jazz kinda thing. Foxx kinda sounds like big muff with octave, and I m not sure if i like Big Muff on bass, and it losses a lot of bass, according to this clip at least http://www.youtube.com/watch?v=wSbwRImjvNc. Couldn't find any RM Octavia clips with bass.
Would increasing input/output caps increase the amount of bass in them?

It all depends on what your looking for. Do you want clean or dirty? For a clean-ish octave up you could try the green ringer. That way you could add you own dirt (if you want it) and get your right sound. http://lynx.net/~jc/greenRingerModded.gif Here's a perf of that too, if your interested. http://www.aronnelson.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=10945&g2_serialNumber=2 I play bass too and I've found some good in a foxx tone machine, or at least Danelectro's cheaper-but-the-exact-same-thing that they call French Toast. the one I've got can be pretty bassy with the tone knob. Just a few mods necessary to get it into the sweet spot.
