EB2-D WIRING PUP MODS

EB2-D WIRING PUP MODS
« on: February 16, 2009, 04:52:16 PM »
hi,
i bought an EB2_D project. i just got the original mudbucker(was thinking of going for a dimarzio) and found a cheap aftermarket bridge PUP that i'm having rewound.
i read on an other post about how to get the true sound of the neck PUP by performing a triple choke bypass (normal/choke/bypass): http://bassoutpost.com/index.php?topic=287.0
inside the body i can see a ground wire that's attached to the bridge post and two other wires that seem to come from underneath the plastic cover. are they supposed to be connected to the choke switch?
 i can choose to bypass the choke altogether (no baritone or mudbucker) and only use one PUP sound (like an eb-0 they say or in my case an eb-3) . super knowledgable forum member eb2 suggested i use the switch  as  a standby switch. that a great idea.
 what other mods can i perform?
thanks

You could try this one that Joe (Chromium) posted a while back - i'm soon to roll my sleeves up and expand this to both pickups of my (newly) white EB3L...

Yeah the other wires will be from the choke.

Let us know what you do - sound clips would be great aswell.

How are you getting the bridge pup wired? To any specific specifications?

Thanks,
that sounds pretty good. i could do that, yeah: 3 way toggle switch : stock/parralel/single coil. i don't know what rewiring the choke would do to me. i don't plan to use the baritone/strangled sound. if i need it, i could just play with bridge PUP on, would kinda sound similar, no? The aftermarket replacement bridge PUP (all parts) is so poorly made, have to rewound it. no specific specs. still is cheaper that to get an orignal PUP which, from what i read here and there, were apparently pretty bad too.
i got that eb2-d as a project. i played with an eb2 once. just loved it. but this time my band mates will for sure want to hear my bass lines and not only just feel them, ;). that's why i'm looking for mods. in the meantime i want to keep that gibson "girth". otherwise i might as well keep playing with a pbass.

I would suggest getting the Donald Brosnac book Guitar Electronics, either buying it or take it out of the library.  It is a fairly quick read, although some of the concepts can require a bit of stewing on.  I think the best part of it is that it has easy to read wiring diagrams for dummies like me - not schematics.  A few days pouring over that and you will have a better idea of the potential, and what you are comfortable with.  One you have the basics down of how pots work and are wired, and what you can and can't do via mini-toggles, you will see that what you can do with that bass is endless.  Although I think your idea of possibly using just the mini-pup is not going to be very nice sounding at all.

If it were mine - and I have an EB3 that I am going to hot rod so same kind of thing - I would leave the choke where it is, and just forget about it.  I like the stand-by switch, and find it somewhat useful on an EB2.  I would hook up the toggle as a main toggle.  I would run the Model One in back with a series parallel push-pull pot on the vol.  Up front I would put in a hot minibucker with a series parallel push-pull pot on the vol.  That is variety enough, although you could run push pull pots on either or both tone pots and have even more wildness going on, like a black ice, which I probably will throw in mine.

All of that is passive electronics.  If you were toying with active tone circuits, again the bass is almost made for them with some nice holes and a big open body to shove things in - all without doing any damage to the wood and tucked away all stealth-like.

Admittedly the mods I mention bypass the idea of the 3 way choke mod.  Which I like as well.  But , that is my idea of fun.  Yours may be much different.

Another mod I thought would be fun is to use a pot instead of a switch to engage the choke (ala the Howard Roberts guitar).  I figure that way you could dial in just a little of the baritone sound without having to toggle between extremes.

I second the Brosnac book.  My copy is old, and I figured it might be out of print or might have been updated over the years, but I see it available on Amazon.  Glancing at the reviews, I'm guessing its still the same content:

"Nice repository of schematics for old, now rare guitars...not just the usual str@ts (sic) and less pauls (sic) that everyone seems to have settled on. If you somehow have an old Gibson SG-1 or a Les Paul Recording model, you'll be able to decipher the mess of wiring inside"

Joe

thanks guys,
it's a bit up above my head but i'll check the bronsac book.
i like eb2 model one set-up but i just got the original neck PUP so i'll go with chrominium's stock/parallel/single coil mods first.
the goal is to have an eb2 that's cuts through like a pbass does and not just carpet bombs infra bass frequencies on stage, which i truly love actually ;) but my bands demands a little more precision.
i'll keep you posted,
this forum is really a gift for all gibson bass fanatics!
kudos to all of you,
dom

1970 Rosetti Epiphone guitar catalogScan of 1970 Epiphone guitar catalogue produced by Rosetti for the UK market. Undated but most likely from mid-late 1970, this was the first UK catalogue to show the new range of Japanese (Matsumoku) Epiphone guitars. Interestingly, these pages show the Epiphone solid bodies with a single-sided Fender-style headstock layout - a feature quickly replaced with a typical two-sided Epiphone headstock almost immediately. Epiphone electric guitars: 9520, 9525; bass guitars: 9521, 9526; acoustic guitars: 6730, 6830, 6834
1971 A World of Guitars by Rosetti catalogueScan of 1971 Rosetti catalogue (UK) featuring guitars from from numerous manufacturers worldwide: guitars by Epiphone, Hagstrom, Levin, Hoyer, Egmond, Eros, Moridaira, Kiso-Suzuki, Schaller, and Tatra.
1971 Selmer guitar catalogueScan of 1971 Selmer guitar catalogue showing the range of electric and acoustic guitars distributed by the company: guitars by Gibson, Yamaha, Selmer, Hofner and Suzuki. 1960s Selmer had always placed Hofner at the front end of their catalogues, no doubt these were the better sellers - but into the 1970s Hofner were slipping somewhat and only appear at the tail end of this publication, pride of place going to Gibson, and to a lesser extent Yamaha. In fact this is the last Selmer catalogue to include the many Hofner hollow bodies (Committee, President, Senator etc) that had defined the companies output for so many years - to be replaced in the 1972 catalogue by generic solid body 'copies' of Gibson and Fender models. A number of new Gibson models are included for the first time: the SG-100 and SG-200 six string guitars and the SB-300 and SB-400 basses.
1968 Selmer guitar catalogueScan of 1968/1969 Selmer guitar catalogue (printed July 1968), showing the entire range of electric and acoustic guitars distributed by the company: guitars by Hofner, Gibson, Selmer and Giannini. Selmer were the exclusive United Kingdom distributors of Hofner and Gibson at the time, and this catalogue contains a total of 18 electric guitars, 7 bass guitars, 37 acoustics, and 2 Hawaiian guitars - all produced outside the UK and imported by Selmer, with UK prices included in guineas. This catalogue saw the (re-)introduction of the late sixties Gibson Les Paul Custom and Les Paul Standard (see page 69) and the short-lived Hofner Club 70. Other electric models include: HOFNER ELECTRICS: Committee, Verithin 66, Ambassador, President, Senator, Galaxie, HOFNER BASSES: Violin bass, Verithin bass, Senator bass, Professional bass GIBSON ELECTRICS: Barney Kessel, ES-330TD, ES-335TD, ES-345TD, ES-175D, ES-125CD, SG Standard, SG Junior, SG Special GIBSON BASSES: EB-0, EB-2, EB-3 - plus a LOT of acoustics branded Gibson, Hofner, Selmer and Giannini
1961 Hofner Colorama IHofner Colorama was the name UK distributor Selmer gave to a series of solid and semi-solid guitars built by Hofner for distribution in the UK. The construction and specifications of the guitars varied over the period of production, but by 1961 it was a totally solid, double cutaway instrument, with a set neck, translucent cherry finish, six-in-a-row headstock, and Hofner Diamond logo pickups. Available as a single or dual pickup guitar, this sngle pickup version would have been sold in mainland Europe as the Hofner 161.
1971 Commodore N25 (Matsumoku)Commodore was a brand applied to a series of guitars produced in Japan at the well-respected Matsumoku plant from the late 1960s to the mid 1970s - and sold primarily (perhaps exclusively?) in the United Kingdom. The models bearing the Commodore name were all guitars available from different distributors with different branding. Although there may have been some minor changes in appointments (specifically headstock branding) most had the same basic bodies, hardware and construction. Equivalent models to the Commodore N25 (and this is by no means an exhaustive list) include the Aria 5102T, Conrad 5102T(?), Electra 2221, Lyle 5102T, Ventura V-1001, Univox Coily - and most famously the Epiphone 5102T / Epiphone EA-250.
1960 Hofner Colorama IIThe Hofner Colorama was the name given by Selmer to a series of solid (and semi-solid) body Hofner guitars distributed in the United Kingdom between 1958 and 1965. The Colorama name actually applied to some quite different guitars over the period, but in 1960 it was a very light, semi-solid, set necked guitar with one (Colorama I) or two (Colorama II, as seen here) Toaster pickups. Although an entry-level guitar, it was very well-built, and a fine playing guitar; certainly a step up (at least in terms of craftsmanship) from many of the Colorama guitars that would follow, and a good deal of the guitars available in Britain circa 1960.
1971 Epiphone 1820 (ET-280) bassBy the end of the 1960s, a decision had been made to move Epiphone guitar production from the USA (at the Kalamazoo plant where Gibson guitars were made), to Matsumoto in Japan, creating a line of guitars and basses significantly less expensive than the USA-built models (actually less than half the price). The Matsumoku factory had been producing guitars for export for some time, but the 1820 bass (alongside a number of guitar models and the 5120 electric acoustic bass) were the first Epiphone models to be made there. These new Epiphones were based on existing Matsumoku guitars, sharing body shapes, and hardware, but the Epiphone line was somewhat upgraded, with inlaid logos and a 2x2 peghead configuration. Over the course of the 70s, the Japanese output improved dramatically, and in many ways these early 70s models are a low point for the brand. Having said this, there are a lot worse guitars out there, and as well as being historically important, the 1820 bass can certainly provide the goods when required.
1981 Gibson MarauderProduction of Bill Lawrence's Gibson Marauder began in 1974, with production peaking in 1978. But by 1980 the model was officially discontinued, though very small numbers slipped out as late as spring 1981. Over 7000 examples shipped between 1974 and 1979, and although no totals are available for 1980 and 1981, it is unlikely production reached three figures in either of these years. These final Marauders were all assembled at the Gibson Nashville plant, and had some nice features not available through the later years of production, such as a rosewood fretboard, and in this case, an opaque 'Devil Red' finish. It's a great looking and fine playing guitar!
