    Does anyone have or know where to get a layout of the tubes for an ampeg svt 2 pro with how the power tubes are matched and what each preamp tube does?
    Thanks....

    I have already read through the manual. I am looking for something more like out of the 5 12ax7s which one is in the driver section and which 4 are in the preamp and out of the preamp tubes v1-v5 does one have more control over the tone of the amp, or the EQ, effects loop etc....
     
  4. I think the driver and preamp tubes are in two seperate lines (if you take the top of the amp off, you'd see what i mean) tho i cant be 100% sure, i just know thats the case with the older SVT-II.

    For reference:
    P1010018.

    You can see the preamp tubes are the 3 near the front, whereas the driver tubes are the 3 nearer the power tubes. Im pretty sure in the SVT-2 pro they are separated similarly.

    Generally V1 (closest to the input jack) will have the most impact on the tone of the preamp section.

    Hi Guys!I have a question for you. Last day I was playing my svt 2 pro and I understood that I really like the clean sound of this head, the problem is that I am also in love with the distortion sound of this monster. I found a level of gain that let me to change from clean to really distorted only by turning the drive knob. Do you think that's possible to put the circuit of the drive into the footswitch replacing the eq switch? i would like to have the footswitch in this way, switch off= drive at 0; switch on= depends on my setting of the drive. Other ideas or possibilities?!

    I don't think anybody but an amp tech is going to be able to answer that, and I'd suspect the answer is no.

    I'm not trying to talk you out of Ampeg, it's just that specific GK amp has a very nice and tubey sound to it and actually has a channel switch so it would do what you want it to ;) Just dropping ideas here because I don't think you would be able to rewire the SVT 2 Pro to do what you want it to because it has a circuit board and those can barely ever be altered.

    ^^^ Yet the GK sounds nothing like an SVT. Nice amp, but not really a replacement IMO.

    Why not grab an OD pedal?

    Turn down the Treble, bump the Hi Mids and no one will be able to tell in the mix. That's the great thing about bass amps, they all sound the "same" FOH ;-)

    I definitely don't agree there. They might sound like "bass" to the audience but they all sound different to me and that's what matters. Take some pride in the music you make.
     
  13. Taking pride in the music you make means being biased more to what your audience hears than what is blowing at your back on stage. Caring more about what sound better to you on stage is not pride.

    The answer to making the drive control foot switchable is no. Sorry.

  14. Anything is possible.

    I recommend you start your own thread with an appropriate title. Might get more of the right kind of attention.

    Most of us consider that taking pride in both onstage and FOH.

    So if the audience really doesn't care (the usual argument round here) and it sounds good enough for them, it must be good enough for me? I don't think so.
    What my audience hears is great bass tone...and what I hear also happens to be great bass tone. I doesn't need to be one sided.

    Go play a gig where you think your tone really sucks. Is it fun? I didn't think so...
     
  18. I've had to sacrifice my on stage tone many times because of the venue. If you are a musician, it comes with profession. I suppose these days IF you have venues with good FOH, your only worry is messing with the FOH engineers. We only have one venue with a system at all around here.

    That's a far cry from switching to an amp you don't like because your sound allegedly doesn't matter. And why even show up if you think what you do doesn't matter? You're only taking up space.
     
  20. Confused? Who is talking about switch to an amp you don't like? If what the audience hears is more important to someone than what they have to hear on stage how is that "doesn't matter"?

    OH I SEE, someone mentioned another amp brand in an Ampeg thread.

    I could sit down with schematics and layout tube functions for the OP, but I no longer have the interest. Someone else is sure to help.
