    i was wondering if i should use a pre amp even though i have a really good tube amp (svt classic). do people generally use pre amps with tube amps? or is it more of a recording tool? i've actually never used one. what would it do for my sound?
    thanks all
  2. A pre amp is necessary to drive properly the power amp, the bass itself hasn't enough output to do that.

    Your SVT already has a preamp built into it. For you, buying a preamp would mean that you'd have to buy a separate power amp too, because you couldn't run this new preamp through your SVT's power amp. If you don't like your current sound, or just want a different rig, this might be a good idea. But if you're content with what you've got, you've got no need for a preamp.

    Some bassists definately use a tube preamp before their solid-state amp, even though the head already has one. I think that one of the most common reasons bassists do this - I mean what it is they want it to do for them - is to attempt, the best they can anyway, to sound like they're playing through an SVT classic. I gather that the intersteller OD is an example of a very conscious effort to simulate valve pre, push-pull valve power stage, and output transformer all together - this is made by SWR.

    Using any kind of outboard processing though - I'd think that you could get an SWR amp closer to the un-altered sound of the famous SVT, than you could get an SVT Classic to sound like an un-altered SWR!

    i'm not sure about the classic. i know the svt2 pro has a poweramp in, and i think the effects loop on the 2 may be entirely post preamp. plugging a preamp output into a poweramp in or into the effects return of an amp that has a post preamp/eq effects loop effectively bypasses the preamp in the head.

    but no, you dont need a preamp if you have an integrated head like the classic. (as long as you dig the tone)

    Just wondering... Can you use a Mesa 400+ as a poweramp? Say i bought a Demeter Pre or GK 2001 pre after i got a bass 400+, I could just use the power section of the Mesa with the preamps, yes?
