I am loving the Joyo Ultimate Drive: it killed at Friday night's gig using my P bass with flats. I asked my guitarist if he thought it sounded good. He said "it sounds amazing!" However, I am having an issue with my one active bass, a Spector NS-2A modified with EMG active PJ set and BQC system. With my passive basses I can set the Ultra Drive to a gain where if I turn down the volume a little on the bass or play softly, it is pretty clean, but gets dirtier the harder I play. With the active EMGs, I can't really do that; it seems like the actives don't have as much dynamic range, or maybe it is something to do with the impedance match. Any ideas why this would be so? Would running the EMG system at 18V make any difference for what I am trying to do?
