Eb3 bass mod
I`ve ordered a couple of Curtis novak bisonic pickups for my Greco Eb3copy. I`m gonna change all the wiring and pickups.
the plan is a 6way 4pole rotary switch for series/paralell and phase in/out switching.
I`ll have independent volum and tone for both pickups, and the tone is going to be a modded fender tbx pot. wich will be able to cut bass or treble on both pickups independently. (hopefully)
the rotary switch is going to be wired like below. the rest of the wiring is in the pdf mod. this is my first mod and wiring schematic, so it may be a bit off..
however, I have a few questions.
does this look like a workable mod overall? I know the volum and tone will not work out off phase (pos 5 and 6). but will It work at all?
what about the series wiring, will the bridge volum and tone pots suck to much tone from the series?
In pos 3 (bridge only) shall I ground the neck pickup, or does this not matter?
about the schematic. the black wiring is ground. I was unable to show the solding on pots etc. the green wire is the hot signal. the square in the middle is the common ground
I have showed some off the rotary switch hope you`ll understand when you look at the picture.
I would really like some help and thoughts about this..
PS. page about the TBX mod here:
this will make it easier. :D
I don't see why it shouldn't work. The switch is definitely properly wired, and the TBX and volumes appear to, as well.
Best of luck with the wiring, and hope you'll post clips when you're done. :D
I`ve chosen a blend and master volum pot instead, and added all the wiring to the diagram.. hope this is more understandable.. ;)
thanks for the feedback! after help on the guitarnutz 2 forum(GREAT forum btw), and studying and thinking, I came up with this new diagram. it also includes a stereo/mono switch and the midchoke on series and paralell mode.
because of independent Volume pots, It also means the midchoke can be added to each pickup if you turn down the other pickup :)
the DPDT switch on the push/pull pot is wired upside down.. to make it easier to see where all the wires are going..
different wiring in the diagram with the midchoke here.
haven`t decided on values yet, though..
I`m just gonna use the inductor from my EB720 and a .47 cap for series and .22 cap for paralell. thats a start.
I`ve recieved most of my parts except the pickups, so I`ll guess I`ll start the wiring soon, to have everything ready for the pickups arrival. However, I came across the Villex passive mid boost, and decided I wanted to have that instead of the midscoop.
anyone here with any info on how this booster work? http://www.villex.com/internal_booster.html
here is a wiring schematic in pdf. only one I found: http://www.villex.com/downloads/switch%20boost.pdf
I`ve tried searching the net (incl. this forum) for info on this but the only info I find is that it is probably transformer or inductor based.. But It has gotten really good reviews also for basses, and thats what I really care about.
I have a question about the wiring. do I need to wire the output from the toneboost straight to the jack output as showed, or can I just wire it to join the other outputs on the rotary? see pictures
What value did you use for the inductor?
last version without stereo/mono switch, but with the midboost on the push/pull and midscoop.. perhaps this is the version I finally end up with. but I`m first going to try midboost and stereoversion. to see if Stereo comes in handy and because of not having to go through all the hassle of finding midscoop values.
I haven`t ordered an inductor yet. but for bass I`ve found that around 3H is a good start.
I`ve found a solution for wiring the midboost with rotary. see pic. this is what I`ll first do when I get the pickup. after a while I`ll probably skip stereo/mono switch to have both midboost and midscoop...
