Hello everyone,
this is my first post, and I'll start off right away, being a newbie:)
My question about V-Tube:
Is it possible to emulate excisting hardware-"tube sound" like an Avalon VT737, or a Manley?
I noticed the three big knobs on the right side of the plugin but I don't excatly know what it actually does...

Hi there

I think that these three values relate to the power calculation for a (tube) amp.

The exact calculation depends on the type (class) of amplifier and the type (diode, triode, pentode etc.) of tube(s).

Typically, they represent supply voltage, output current and load impedance.

Lots more information here:

Hi Counterparts!

Thanks for your reply.
I am however the worst, when it comes to
electronic circuits.
I have a very basic understanding of volts, ohms and amps.
When I, for example take a look at the specs of a tube mic-pre, or tube-eq, compressor,limiter,whatever, I usually see the following:

-Circuit topology: Four dual triode vacuum tubes, high-voltage discrete Class A

-Gain Range Microphone: Transformer balanced 850/2500 ohm, 0dB to +58dB

- Maximum output level: +30dB balanced 600 ohms, DC coupled, discrete Class A

-AC power Internal toroidal 100v to 240v, 50-60Hz selectable, 75 watts maximum

This is just an example.
Where must I pay attention to, I mean if I want to determine the amount of ohms, should I look at the "gain range microphone-section" or at the "maximum output-section"?
And how do you determine the amount of amps?

Again, I'm a total ass at this, but I just want to be able to dial in correct settings.
And just trusting my ears won't gain more knowledge about electrical equipment :smile:

To be honest, I reckon your best bet is to download the VTube demo and play about with it!

I gleaned the information I presented from the page on dadev's website which I posted a link to...I'm certainly no expert.

My personal experience of valves (tubes) is ... when I was a kid and the television picture dimmed, a bloke used to come round to replace the burned-out vavle with a new one! :smile:

Hmmm....well I'll try to obtain a manual from Dadev.com,if they have one.
Thanks again for the info!
I'm sure to call the guy you know, when my TV breaks down :wink:

Cheers!

If you are looking for software good sounding tube sound, get the Celmo's BAM! There is nothing like it:

Oh, I'm sure that it will sound just great.
But that's a bass-amp sim; I'm looking for something to simulate the tube-sound of pre-amps, comps, and eq's like V-tube apparently does, and apply it to vocals mostly...
The only thing Dadev doesn't describe, is which settings for impedance you have to apply: at the input or at the output stage?
It's almost as if the people from Dadev assume that everyone knows how to dial in correct settings.
But as I said before, I'm a complete ass with electronical knowledge :smile:

But thanks anyway!

The VTube's very likely to have a bunch of presets which might help you to interpret the dial settings.

Does nobody at Z own one of these things?

yes it could be usefull sometime but big big phase probleme between dry and wet signal and strange knobs behavior ( again the dry and wet knobs ..) BUT with the right setting it sound good and subtle.
