    Just curious on the general concensus. V-V-T or V-V-T-T?

    I have one setup each, to me it seems that V-V-T is not only easier to deal with ,but it also produces more tonal enhancement...say comparing the total high roll-off of 1 tone pot 1/2-way; compared to the total high roll-off of 2 tone pots 1/2 way (meaning both tone pots rolled off 1/2 way).

    all things being equal, 250K pots, linear taper. Although the 2-tone setup uses two .473mF caps, the 1-tone setup uses a single .5mF cap.

    Why such a dramatic difference? or am I just tone-deaf?

    I prefer V-V-T. I don't need an additional tone control.

    It is impossible to isolate pots from each other in a passive circuit. Current flows equally both ways.
    As a consequence a double tone pot is useless in a passive circuit unless you have switches to select pickups. Both tone pots will act on both pickups.
    I too prefer v-b-t.
     
  5. It is possible to a certain extent by using mixing resistors, but that makes the whole setup a lot more sensitive to external loading and cable capacitance than it already is...

    Anyways, I'll "third" v-b-t

    If we are talking about J's with vintage style, single coil pickups - I prefer the 62 RI style stacked pot approach. Yes it's slightly darker than the V-V-T but - those bassses can usually stand a little darkening.

    I have yet to hear a passive VBT that works as well as an active blend. So I keep an active J, passive in VVT and passive stacked VT, VT in my stable.

    My VVT bass has 5 % overwound on Alnico magnets from Vintage Vibe abd that setup works really well as the pickups are a shade dark to begin with - not muddy at all, just not 'zingy' bright. That one is an Ash body & maple neck so it can stand a little taming. Being a 75 RI it would just not be right to drop the stacked controls in though ...
     
  7. Most active basses use a passive blend and not an active blend (The only one I can think of that does is the audere)

    Hmmmm, I like V-B-T.

    But, the Master volume is a push/pull pot which switches between series and parallel. And there is a switch next too the tone pot that scoops mids out. The call it a 'Slap Switch' and squire use them on their deluxe 5-strings.
     
  9. I used MV-V-V for many years - no tone controls at all!!

    My current bass has Volume/Blend. It's eventually going to get a preamp (probably an Aggie OBP-2) but when I was assembling the bass, I was lazy and decided to do it passive for now. LOL.
     
  11. That's an odd choice... why not go V-B? Same thing really and one knob less (third could be replaced by a series/parallel switch)

    I've got this configuration with some Dimarzio model J's. Yeah, baby! :bassist:
