    I have a geddy lee jazz bass which has a seperate volume control for each pickup. Now dont get me wrong i love my bass, but i hate having two seperate volume knobs. My band's guitarist always cranks it for "Roadhouse Blues" so then i have to turn up as well, then turn down again. I would prefer to do so on my bass rather than amp.

    i always have both pickup vol. at ten as i like the sound of both pickups maxed.

    so the question is, w/o spend alot of money, or any money, can i solder one volume knob to work with both pickups w/o doing any damage?
     
  2. No, you can't. You would need additional electronics and/or a dual potentiameter. Just put a rubber band around the volume knobs so that when you turn one, it rotates the other as well. :D

    That's what i'd do.
     
  4. Couldn't he wire the pickups in parallel / series, and then use just one pot as the master volume?

    Wrong forum btw... I think.

    Why can't you have a passive blend with a master volume?

    +1 It's the same # of knobs, but one controls the balance between the 2 pickups (in the middle would be equal amounts of each pickup.) and the other controls the volume of the signal coming from that.

    How do i go about doing that? Is there a website that shows how to do such wiring jobs?

    If it will actually work, that is. :)

    You would need 25K vol/blend pots instead of the 250k most passive wiring diagrams show. Apart from that, the wiring is the same.
    And just to clear up any potential confusion: you can have active pickups and passive wiring.

    thanks! i dont' suppose they have these pots in a radio shack? where could i get 'em?

    and i never (and probably never will) understand the whole active this but what a passive that thing.

    places like that will have 25K volume / blend pots
     
  15. My suggestion is the master volume/master blend setup. My Jazz is setup that way.

    i've got my MM jazz wired: s/p toggle-single vol-preamp and have had no problems, but with it set in series the low E(or D in my case) sounds way too loud and boomy(much louder than the other strings) so i'm gonna remove the switch and just have it hard wired parallel to the single volume knob, or even just bypass the vol knob and go straight into the pre and use a vol pedal if i ever need it.
    but i'm not 100% sure if you'd need a different vol pot to have both hard-wired to the same one w/o a switch. right now, mine's wired up to the stock 250k pot with the switch and haven't had anything bad happen, so again, i'm not sure if removing the switch would necessitate changing volume pots for it to work properly.

  18. Yes, master volume and blend pot will work just fine, as mentioned all you need is some new pots which are cheap, and some minor soldering work.

    Very easy and just fine to do ;)

    Since we're on the subject, are there any disadvantages to using Volume/Blend over Volume/Volume?

    I've been thinking about changing the setup in my Mike Lull bass from 2 volumes to volume/blend, but before I try it I would just like to know that I won't be sacrificing anything. :)

    Also, if I wanted to add a switch in the future for running the pickups in series, is there any way I could make the switch bypass the blend pot? I remember someone saying that on a Vol/Blend bass running in series, the blend would have to be fully clockwise for it to work right, so I was just wondering if it would be possible to avoid that.
