Couldnt even find a thread addressing this issue...
I'm planning on getting one of these, not sure which one would be best.
Here's my observations from my research:
VFB is only $10 more, so price isn't an issue
VFB has a feedback option
Jr. is physically smaller
Is the feedback option worth it for a bass or just a cool idea? My band is kinda coldplay sounding (ie not ugly angry sonic mayhem) so I don't need a-pig-getting-skinned alive sound but unique sounds are good with me

Size isn't a huge issue to me at this point since I don't run many pedals currently, but it is good to look ahead. Wait a minute..with this one...and my undying gas for a bassdrive i just might suddenly be at 5....
So yea..basically it's whether the feedback is worth the while, sound clips would be a great plus since your opinion may be irrelevent to my ears anyways...
Thanks y'all!
