    I am thinking about modifying the wiring of my Rickenbacker 4004 Cheyenne with a Jazz bass setup Vol Vol Tone or keeping the switch and doing a stacked configuration.

    I have been reading a lot here that people have had success with one or the other of this type of modification.


    But I can't find what specific parts I need to get or if I need to make any physical alterations to the instrument like routing or drilling holes.

    Any addtional help would be appreciated.


    Thanks
     
  2. You will need a concentric pot and knobs for it. A500k/A500k would be preferable, or B500k/B500k, if you can find one.

    If you want to drop in a volume where the switch is, you'll need to drill.
    I would recommend all new pots, get at least 500k Ohm, and you'll notice more brightness.

    The first one to get a VVT setup. :) :D

    I drilled the switch hole out for the 3rd pot, but I also went a step further and moved it slightly higher up the body so that all three pots were equidistant (not necessary but that's what I wanted to do). To make sure there was adequate room for that pot in the control cavity without hitting the side wall I used a Forstner bit to route out the upper end of the cavity a bit.

    I did a few other mods to the bass but none that contribute to the harness, beyond making my own harness using 330K (within 3% tolerance. I had a bunch and measured them to find three that were right around 330K) Clarostat CP linear pots. I still have the harness as a subsequent owner returned it to me when he did some other mods to that bass (he was also kind enough to return the Hipshot A Style bridge to me, nice gesture on his part :thumbsup:). But, he kept the toasters. :crying:

  5. For future reference, resistance is not critical. You wouldn't hear much of a difference if you were 10 or 20 percent off spec.

    Capacitors are a different story, though.

    Yeah, I know, but it was fun to see how close I could get out of a dozen of those pots I had laying around. More academia (time wasting) than needed. :smug:

    What type of pickups are those? I was planning on keeping the stock HB1 pickups. Do I need to change the pickups, too?

    If I do concentric setup, do I need a special wiring harness?

    wiring harness is just a fancy term for pots, cap(s), and wires pre-assembled

    all you'll need for a concentric pot install is more wire

    I much prefer the sound of the HB1 humbuckers over the "toasters" that Jeff has installed. Maybe he can post a clip of how it sounds so you can decide.

    Thanks for the input. I will look into getting me some new parts.

    You can have your standard hb1 pickups wired with coil taps,and get a sound fairly close to the single coil toaster pickups pictured in Jeff's bass. I've done that option on 2 of my 4004's. I have another 4004 with SC pickups in it,as well as an old 4000,so i'm able to compare them. The tapped hb1's are not *quite* as glassy,but they sound really good.
