I take it that if a Modulus VJ bass was active, that there would be a battery plate on the back of the body - correct? Or do they put the battery under the control plate on the front? Also - does anybody own a passive VJ? If so, I'm sure it sounds drastically different then a VJ w/ active electronics. I've seen some VJ's around but w/ no batt compartment so I've assumed they are passive. I'm just wondering what a passive VJ sounds like w/ EMG's in it. Any feedback would be appreciated!
