I have owned the EBS Microbass II for quite a while, and frankly, I'm disappointed.
I use an EB Volume pedal as part of my signal chain, which is run thru the effects loop in/out. When I take the vol. pedal all the way down, I still get sound coming from my bass, which immediately defeats the purpose of a volume pedal. Imagine trying to do swells with delay and a bit of distortion, and still getting that sound exactly where you don't need it? Ouch!
Adding to that the constant loss of gain, the signal dying out on me in the middle of a show..., last saturday my patience really got tested with that pedal. I opted to remove it and running directly from the bass into the pedals, and then into the amp, and the volume pedal worked perfectly, no soud with the heel all the way down, the way it's supposed to be. Too bad, of course, because the original reason why I bought it was to use the A/B switch (I also use a fretless on stage, besides my fretted 5 string), and the effects loop, of course.
I used to use the Bassbone before, which I replaced with the Microbass II, because I thought it would be a better choice.
I've been told that I can operate the FX Mix knob to get to a "sweet spot" whre the vol. pedal will work just fine, but that spot doesn't seem to exist.

Since everyone here seems to have mostly positive opinions on this pedal, I would kindly appreciate your input on this.
Take care!
