Gibson EB0 circuitry

Gibson bass guitars | EB-0 bass main page | technical information

The EB-0 bass had the simplest of circuitry, two pots, one each to control volume and tone, an input jack, and two capacitors. The value of the tone pot (and capacitors, but see below) did change slightly when the pickup position was moved away from the neck to a more central position in 1972 (see a 1972 EB0); and there may have been instances where unusual value parts were used, either for experimentation, by accident, or to use up stock - if you have an EB0 with non-standard circuitry, please comment.

Potentiometers were typically made by Centralab (code 134) in earlier examples, and CTS (code 137) later on. There was significant cross-over with looms with a pot by each maker also common.

1961-1971 EB0

1960s Gibson EB-0 wiring schematic

Gibson EB-0 circuit diagram from the 1960s. Note each pot has a 500kΩ resistance and capacitors of 0.01µF and 0.033µF. This diagram also corresponds with the Gibson parts list of January 1965 which lists the EB-0 as having identical volume and tone pots: part number CBA-811-1053. Pots used were typically produced either by Centralab or CTS.

This schematic is correct for the Gibson Melody Maker, and Kalamazoo KB basses.

The two simplified wiring diagrams below show the precise connections on the looms of early examples.

Early 1960s Gibson EB-0 circuit illustration

The above illustration demonstrates the exact circuit connections in the schematic above, from 1961-64 approximately.

Have a closer look at some actual looms using this circuit

Wiring loom from a 1964 Gibson EB0 bassThis 1964 EB-0 has the same circuitry but a smaller value (250kΩ) tone pot. Click for further details.

Mid to late 1960s Gibson EB-0 circuit illustration

This illustration shows effectively the same circuit, with slight changes to the wiring of the .01 µF capacitor; in each case it sits between the volume pot contact and earth. This circuit variation starts around 1965.

Have a closer look at some actual looms using this circuit

By the time of publication of the 1971 Gibson parts list, the suggested potentiometers for the EB-0 are parts 70027 (500kΩ, volume) and 70021 (250kΩ,tone); one would assume that this refers to the slotted headstock models in production at that time (and not the newer, maple-necked, solid headstock basses that would replace them), in practise the majority of these basses actually seem to have a 500kΩ tone pot, often part BA-811-1158. What is pots are in your slotted headstock EB0? Please comment.




Early/mid 1972 transition EB0

Early 1970s transition EB0 wiring

This circuit is an intermediate between the 1961-71 and 1972 onwards circuitry. Exactly how common it is is not clear, but it was certainly used for a brief time in early/mid 1972. It has the capacitors of earlier looms, yet has the 250kΩ tone pot, typically seen on post '72 EB0s.

The pots used at this stage (in the few examples of this loom I have studied) have been a mix of CTS and Centralab (seen an exception? Please comment).

Typical 1970s Gibson EB0, 1972 onwards

1970s Gibson EB-0 wiring schematic

Gibson EB-0 circuit relevant to EB basses circa 1972 and onwards. The tone capacitor values and tone pot resistance have both been lowered, having a subtle effect on tone: dropping higher and lower frequencies, and boosting mids.

What is the purpose of the extra .01 capacitor?
Andy Comment left 21st May 2019 04:04:00 reply
The 0.01 cap kills high frequencies. I used to own both a EB-4L and an EB-0 (slotted headstock). If I had known this cap was in there, I would have disconnected one end because the cap makes the bass so dull and muddy. Way back when these basses were made, (in my opinion) Gibson and others wanted to simulate the tone of upright basses. Anything that sounded clanky or too treble-y would have been undesirable. I recently purchased a Gibson SG bass (made in 2012) and I checked that there was no 0.01uF cap installed. My ears told me it wasn't there, but I had to look inside just to be sure.
Terry Falk Comment left 15th December 2015 22:10:40 reply
I have a 1966 EBO which I have owned since 1969. I never messed with the tone control(always all the up) because it never sounded good. After 40 years I decided to investigate and found that the .033 cap was soldered to the top of the tone pot instead of the wiper. I believe it was always that way because the solder joints appeared to be untouched. I had the bass refinished by Gibson in 2010. It is wonderful and since I have no desire to ever sell it, I don't care if it affects the "vintage" price. Regards, Terry Falk
