    I am running a P bass -> ART Tube MP -> Behringer EP1500 -> LDS cab.

    The real problem is the Behringer, I have it maxed out and am not getting enough volume. I know I should replace it with a better power amp or get a second cab, but I am looking for a cheap solution since this rig is just used once a week for practice.

    I have the preamp running with over +30dB gain (gain and volume at 3:00). Any more gain and the pickup hum becomes very noticable when we stop playing.

    1) Would a noise gate in front of the preamp solve the problem? Or is the pickup hum too low to trigger it? This is a fully shielded bass and is very quiet. It is only the high gain that is causing problems.

    2) If a noise gate in front of the preamp won't work, are there any inexpensive line level noise gates. I want to spend $100 or less.

    3) Will a Boss NS-2 work? I have heard people complain it does not do much for cutting guitar hum.

    :rolleyes: Where did you hear that? I find it works perfectly if you stick the gain causing stuff in the loop. IME it actually negates a lot of the hum, even while actually playing a note!
     
  3. Put simply, a noise gate will only assist you if you can put it after the source of the noise.

    If ALL the noise is being generated in the pre-amp, you need to put it in the effects loop. If however it's being generated by the bass and just exacerbated by the pre-amp, it might help to some extent.

    A noise gate for a bass amp is a band-aid solution at best.

    Focus your attention on eliminating the source of the problem, not covering it up.
     
  5. yea a gate won't really get rid of any hum/buzzing noise totally.. ur gonna have to tweak something in the bass or the pre-amp
