Just got a new roscoe a few days ago. When I first got it and played it through my eden rig it had a normal output. Now after a few days the output seems very very low, I no longer have the eden and when I tried to play it through my ALembic f-1x/ crest ca9 rig I had to turn it all the way up to even get the signal indicators on the crest to light up at all. I changed to batteries and that didnt seem to help. This bass has an audere pre and it is brand new. What could be the problem!
