    I'm probably not going to perform the actual mod, but I've been thinking about what if. I'm new to messing with bass electronics, so this is more of a thought exercise. What would you do and why? Are there options that I completely missed?
    -----------------------------

    I have a warwick corvette 5 rockbass double buck (I don't think I got the order of words right lol). Passive. There's two volumes and a tone, but also each volume is push-pull to put each humbucker in series or parallel mode. The cavity is a generous enough size that I shouldn't be cramped for space if the wiring gets complicated or I have to add controls.
    I like blend knobs, at least in theory. I see two potential solutions if I really wanted that blend knob:

    1: Volume + Blend + Tone, with one of them being a push-pull that switches both of the humbuckers (Is this possible? Can a double pole do that?).
    Pros: No drilling needed, external appearance is still the same.
    Cons: I can't put one pickup in series and the other in parallel anymore. But then again, I don't think I ever use that. Compensating the volume differences in that situation is pretty annoying, and my ear isn't picky enough yet.

    2: Volume + Blend + tone, with switch(es) for the series/parallel options. Probably 2 linear switches, but could be a single rotary switch too. idk.
    Pros: You can still control series/parallel individually per pickup, and those push-pull pots were too easy to push in by accident anyway
    Cons: Drilling / routing required that could potentially go horribly wrong. Maybe a bigger resale value hit?

  2. The series parallel switching uses both poles of the typical 2 pole switch switch you find on push pull pots. You could go volume, blend, tone and have the volume and tone pots be the push pulls.

    Well, I looked up more about push-pull pots and I feel like an idiot... Somehow I imagined the switch and the knob circuits to be tied together somehow instead of being completely separate.

    I feel like individual push pulls on top of master and tone could be fundamentally confusing but I'd get used to it fast enough. It really doesn't seem like there's a better way to not lose functionality.
     
  5. I have read that there are blend pots with a switch built in but I’ve never needed one so never looked personally. Can’t imagine they’re cheap, though.
