I play through DI only in our wedding band and after reading a lot on our forums about how an active bass (or certainly one with a buffer) will lose less signal quality/high end than a passive when the cable is over 20 feet long. My question is this: Given that this is the case, id like to get some perspective on this. If you had two idential basses except one has no onboard preamp, how much volume and treble frequency are you going to lose using - say, a 40/50 foot cable? What frequency range is the passive going to filter down to and how many db of volume are you losing. More importantly what is the extent of the perceivable loss? Thanks.
