At the tail-end of the 1960s the Gibson EB3 was redesigned; the most immediate change being the new slotted headstock. It still came in Cherry, but also Walnut as seen here; a lot of slotted headstock EB basses were shipped in walnut finish
1971 was the last year of the slotted headstock EB models; their short production run started in very late 1969 (the earliest models have no 'MADE IN USA' stamp, and very early 1970 pots - see an early slotted headstock EB-0 bass) and ended in late 1971. A very small number were also shipped in 1972, although most likely limited to custom-order basses, such as this left-handed EB-3 that was ordered a year earlier.
The bass shown is indeed typical of it's vintage: three-piece bound mahogany neck without volute, one-piece mahogany body, five-ply pickguard, scripted truss-rod cover and glued-on pearl logo. The six-digit serial number is stamped in to the neck above MADE IN USA. As a 30 1/2" scale instrument, it requires short scale strings.
1971 Gibson EB-3 specifications
Hardware includes the two-point intonatable bridge with cover, Schaller M-4-C tuning keys, and Gibson neck humbucker (lovingly dubbed 'mudbucker') and bridge pickup. There are a few minor differences to 1970 models; in 1971-early 1973 a lot of EB basses had 'Gibson' etched into the pickup covers, and string mutes (although never universally fitted) were phased out. Few later production slotted headstock EBs (or 1971 Gibson basses in general) had them, and they were completely discontinued by the advent of the maple-necked EB basses in late 1971. (See a 1972 Gibson EB-3)

The slotted headstock EB3 was first shown in the 1970 Gibson bass catalog. This is one of 706 walnut EB-3s shipped in 1971, (compared with 973 in cherry and 25 natural) and one of approximately 3644 slotted headstocks shipped in total. (The production run of slotted headstock EB3s ran from very late 1969 until very late 1971, whilst the figure quoted is for all EB3s shipped in 1970 and 1971. It may exclude a few very early split headstocks EB3s and include a few of the later maple-neck EB-3s. See the EB-3 shipping totals.
In 1971, the EB3 had a US zone 1 list price of $410 - plus another $90 for the case.

Another 1971/72 feature is the Gibson logo on the cover of the Gibson neck humbucker and bridge mini-humbucker.





This circuitry is broadly unchanged since the very first incarnations of the EB3 bass.

Hi where can I find the value of my 1971 EB3 Gibson bass guitar? Someone wants to trade me for a 1975 Fender Mustang is that a fair deal? My EB3 is all original including the electronics and no damage ever although the neck is slightly bowed and needs to be adjusted. Thanks Linda
