i got a chance to buy a radial jdi for a good price and did some serches but they mostly relate to guitars and not bass. i would use it just for bass and im using a $50 rapco passive di for bass now.it does the job but im thinking i would notice a difference with the jensen transformer in the jdi. think i would? anybody using it specifically for that or should i be looking at something else for bass(active di)?(for a passive p-bass, if that makes a difference). thanks,any thoughts would be appreciated.
