Trace Elliot V-Type Tube Preamp Question

Discussion in 'Amps and Cabs [BG]' started by diptixon, Sep 11, 2005.

    All, just purchased a Trace V-Type preamp that I am running thru a Mackie M800 power amp bridged into an Avatar 210 or Peavey 410 cabinet. I am pleased with the sound, but the 'bright' switch on the preamp seems to be very, very subtle; I can barely hear a very small difference in tone when it is switched on, with a tiny bit more 'hiss'... the 'deep' switch, however, does make a very noticable difference in tone.

    Are there any other V-Type preamp owners on the board, and if so does your bright switch act the same way...?

    Also, I know that this preamp is similar in design to the Alembic F-1X, which has a bright switch as well; for any owners out there, how much does the switch on the Alembic affect the tone...?

    Thanks, Danny

    It's the same with my V-Type 300H head. The bright switch has very little effect, while the deep makes a huge difference in sound. I bought my 300H NOS so I imaging that's how it was designed. I can still get plenty of high end out of it with the mids and treble pots.

    natrab, thanks for the info... j-raj replied to a PM saying that his Trace v-type preamp's 'bright' switch DOES change the tone a good bit for slapping, etc., so I'm really not sure if I (we?) have an issue or not... I may bring it in to be checked out...

    you might be comparing this way, but listen for the difference when you are slapping, not finger type playing. The slap switch will effect the slap sound more then it will effect the finger style sound.... at least it will be more noticeable. The Trace V-type preamp is a very under-rated pre, its one of my favorites! The mid shift push/pull is also a very nice option.

    Yeah, fingerstyle, I don't notice it as much.

    When slapping, it gives a fair bit more 'zing' to the top end. And considering mines all tube, it's a pretty good zing as well :p

    Ah, yes, now I see... thanks for all the input, when I slap is when I can hear a difference, a bit more top... very nice. My previous amp was a GK 400 RB, and I guess I was expecting the 'bright' switch on the Trace V-type to act like the 'hi boost' on the GK; evidently it is not intended to do the same thing...
    thanks, danny

    If the V-Type and F1-X are truly based on a Fenderish tone stack, the bright switch should have little effect at high gain settings.

    In a Fender style preamp, the bright control uses a single capacitor to pass some high end around the volume control. As the setting of the control approaches maximum, the effect diminishes, disappearing completely at full blast...

    I don't know if these two preamps are that Fenderish though...

    the manual i've got for my v-type copies that. i haven't tried it though.

    Yes, I notice that in the Trace V-Type Preamp manual, it states the bright switch is disabled at maximum gain due to the nature of the circuit...

    FWIW, Similar behavior is seen on the Zvex nano head guitar amp.

    Bright switch only works at low volumes. Given that the amp is only 1/2 watt, that is a very low volume.

    I know it's probably too late, but I just got a V6 and I am surprised at how hissy it is. It's still got the original tubes and they most likely need replacing. The first thing I noticed was the hiss and the fact that the bright switch seems only too add to that. The deep switch works great but same opinion about the bright switch.

    No issues with bright switch hiss on my V4, although sadly it has developed another issue which will need attention before I take it out again.

    Makes a "rushing" noise as well as the bass signal. Used to do it occasionally but now pretty constant Hopefully just a preamp tube but may well be a capacitor. I have three other tube heads so have not rushed to fix it.
    Note to self.....fix it..........
