active bass confusion.

Discussion in 'Pickups & Electronics [BG]' started by metro_trash, Aug 6, 2001.

  1. A passive bass uses a potentiometer ( or a couple )to roll of treble for tone giving you limited E.Q options as. This I understand.

    I've heard of 3 things active pickups , active E.Q and basses with preamps.
    Active E.Q lets you boost treble and bass by adding gain via power supply ( ie. 9 volt battery )
    My bass has a bartolini pre-amp which has switchable e.q , besides added gain what does this do for me... can I plug a bass with an onboard pre-amp into a power amp and play?
    Active pickups.... is there such ( well yeah ) a thing and how do they work?

    Active Pickups: Need power to work. Ie: Most EMG´s if not all.
    OnBoard Preamp and Active EQ are the same thing.

    Can you play directly to a Power Amp?
    Yes and No.
    It will work, but the output of the Bass is more suited to work with another preamp, the signal is too low to be properly amplified by a Power Amp.
  3. Yes, there are things such as active pups...I should hope so otherwise I have some very odd black boxes in my SR-885 ;-)
  4. if i have active pickups and passive electronics do i put my cord in the active input?
    and if i have passive pickups and active electronics do i put it in the active input?
    can anyone explain the difference between passive pickups and active electronics and active pickups with pass electronics?

    the first case is for example the G&L L serie
    the second, for example the emg pickups
    differences are hard to say but i prefer passive pickups with active electronics because you can have the true passive sound too, that's impossible with active pickups. and the passive sound is for me the best by far.
  6. My Cort Artisan 5 runs a 9 volt battery for the active Bartolini mk1 pickups. I prefer active basses becuase it makes the bass sound more alive. Much brighter and deeper without being harsh.

    I think most people are confusing active pickups with active preamps. If you have the 2 or 3 band EQ, you have an active preamp. Active pickups aren't very common, and don't give you any EQ options, they just make you louder. The preamp also makes you louder, but gives you the EQ options, which is why it's preferred.

    My understanding of active pickups is that they have a much less powerful magnet, and need a current running through them so the signal coming out of the pickups is boosted just enough to work with the preamp. All the basses with active pickups I've seen also have an active EQ section. Then again I might be wrong.

    Can someone tell me a maker of an active pickup? That is a a pickup that requires current that is not part of a preamp system? Please don't say EMG, because EMG pickups have preamps. They are built into the pickup itself.

    As far as I know, all active pickups have preamps, the difference being that the signal is preamplified in the pickup itself. (Kind of like how a condenser mic works.)
