SB series bass. Who am I.

SB series bass. Who am I.
« on: February 19, 2011, 04:08:30 AM »
Hello all. I have been gleaning some info from this sight for a while now trying to figure out what my particular bass is. Like others here I share an interest in the early Gibson bass guitars. Mainly anything from Kalamazoo . There is a lot of good info here along with some photos and it is pretty clear from scanning the web that handmade instruments don’t always look exactly alike from instrument to instrument. Parts seemingly borrowed from one model to the next.

I got my bass in a trade for a crybaby wah wah pedal back in the very early 80’s. Where and why I had the pedal, I just can’t fully remember.  $35 dollars comes to mind. Where the bass originally came from I don’t know either. However I do know what it looked like. Someone had taken a blow torch to it to apparently put stripes  on it. I kid you not. The bass was completely bare of paint with burn marks all over it. I painted it with the only color that I felt would fully cover the burns: black. I did not paint the neck because I like it like that. Pure wood.
 
With all of the stripes on it I thought that maybe the person burned off all of the finish. It never accord to me that the finish might have been natural. When you go out online and see photos of guitars that look like yours but aren’t quite you can only try to put the pieces together and come up with a possibility.

Look closely to the photos and you can see that the neck is in the body much deeper than the normal SB400. And when you compare photos of the sb300/400 neck and the sb350/450 neck they appear to be different. The specifications say 2 piece for the sb300/400 and the photos back it up.  Is the sb350/450 a 3 piece neck? And does the headstock have 2 pieces on the sides?

The body is the classic sb series but the pickups have been slightly moved down. All of the photos you find online show the bridge pickup almost lined up perfectly with the sb300/400 body contours. The pickups are obviously the correct ones but the location for the bridge pup is almost inline with the control panel. Also not normal. The bridge is an obvious replacement but was there when I first got it so it is also quite old. It is brass and fairly heavy.

The tuning pegs are the Schaller m4 series so that is correct for the sb300/400. The control panel knobs are not original. (would like to get some if someone has any) And the nut is not correct. When I look at photos of the nut and the fingerboard/truss cover It seems that there are narrow ones and wide ones.  The space from the fingerboard to the truss rod cover seems to change from model to model.  Does anyone know if there is a specific nut for a specific model and its dimensions? I carved the one I have from a bone stock.

So what is it? An sb400 with the wrong neck? An sb450 with the right neck but wrong body? It does not match the ’73 sb450 model add that is found around here somewhere.  Is it possibly an sb450 from ’72? There were very few made and maybe it was decided to make a bit of a change for the new ’73 model?

Looks long scale, so 400.  I can't guess what is up with the headstock nut area.  Fun basses, I think.

late Gibson SB400 bass?

That is an interesting bass, thanks for posting. This is definately an SB400 rather than an SB450 - the pickups are what denote this really.
 
Gibson always wrote something along the lines of 'we reserve the right to change specifications without notice' - and they did. Any instrument that was made for any period of time evolved continuosly, with little changes here and there.
 
Assuming that this is all stock, my guess is that this is a very late SB400. Some were still being produced after the introduction of the SB450 (albeit in very small numbers - see the Gibson SB bass shipping figures) - and i'd suggest this bass is one of those.
 
Do you have a serial number or some pot codes? I can probably narrow it down a bit with the serial number - the earlier SBs had pot codes dating to 1966 - so 1972 codes for example would be significant.

Jules. Here is what I have been able to get off the bass:
serial number: 122680 (can't see it very well so I can't be sure)
tone pot: BA811-3701-205K-BA6635

The one thing I notice about the serial number on my bass compared to other sb-400 serial numbers that I see on-line is the typeface is much larger on the later ones then the early ones. The typface on mine is larger so you may be onto something about it possibly being from '73.

I wonder if they actually did make a (possibly) natural finish sb-400 with pickups in a different location and a neck from the sb-450 series. Wierd.

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!
