    I have both an active and a passive bass. I have a GK amp which has input jacks for either. I usually run my bass through a Zoom B2.1U. Any thots which is more correct?

    Always try the passive input first. If the amp distorts or clips, switch to the active input.
     
  3. The active input is for any device that has a built-in amp or pre-amp.The passive input is for unamplified inputs, such as basses without batteries.

    And plenty of people use just the passive input, even if they have active basses.

    Like me :smug:

    Active basses go in the padded input, otherwise you won't be maximizing headroom.

    Plug an active bass in the passive side if you want a hard clip and (in my experience) and poor tone.

    My old SVT's padded input was -15db which I found really quiet, I tried everything in my power to run my BTB (18v) through the passive input, to get any noticeable volume would cause hard clipping.

    That's entirely dependent on the bass and amp in question, and pretty much BS as a blanket statement like that.

    I've never had an issue with clipping or poor tone.

    So much this...
    I've only owned 1 passive instrument in my life (about 15 years ago). Been using Actives into the Passive Input only since that time.

    Ok: question tho--
    I play a jaguar, and typically keep it on passive setting, unless I'm playing a solo and want the boost from the active switch, then switch off again--which jack is best?
     

  12. There is only one reason to ever use the padded "active" input...........

    If when using the unpadded "passive" input you experience clipping. Other then that, you want the hottest "non-clipped" signal going into the amp.

    my GR is- unless you're just frying your preamp/front end, use the Passive input. Sounds way better. Even on hot 18V Spector preamps I don't have an issue and run my Mesa's Gain at about 1:00.

    the reason to go into the passive input with the active bass is if you want to sound like NIN :)

    Not familiar with Spector preamps, but most 18V preamps don't have any more output than 9V...just more headroom before clipping if the pickups are extra hot.
