The guitar boom of the 1960s created a huge market for entry level guitars, and high-end American guitar manufacturers were repeatedly undercut by overseas manufacturers. This ultimately lead to many well known guitar companies moving production to Japan; re-branding imported guitars to fill the lower end of their ranges. In the 1970s, Epiphone guitar production was subcontracted to Aria, who had them built at the very well regarded Matsumoku factory. And the very first solid body bass in this range was the Epiphone 1820, which would soon be better known as the Epiphone ET-280 bass.
In the 1960s Gibson and Epiphone were complimentary brands, both owned by CMI, and made side by side in the same factory, to the same standard, and effectively filling the same position in marketing terms. These guitars were aimed at professional musicians, and were priced far above the student and intermediate models coming from Japan. A third CMI brand, Kalamazoo, to some extent offered lower priced guitars and basses, but with US production and Gibson-made parts, they still were not cheap enough. And Japanese guitars were getting better and better all the time.
Norlin took over Gibson / Epiphone ownership in late 1969, leading to a significant reorganisation of the company's brands. Gibson continued to manufacture high end American-made guitars, Epiphone production was moved to Asia to build entry and mid-level instruments, and Kalamazoo was discontinued. From a business point of view this was a complete success, replicated by many other companies, and a model that continues to this day.
The Epiphone 1820 / ET-280, was the brand's first solid body bass from Japan, and was a complimentary model to the Epiphone 1802T (ET-270) guitar, and 5120 electric acoustic bass. It was first listed in the October 1970 Epiphone price list, although it is not certain it was available in stores this early; it was standard practice to list new models in prices lists some time before they were actually available. It was a solid instrument, with a hardwood body and bolt-on neck, a nice rosewood fretboard and two single coil pickups. Controls were simple - a master volume and tone with a three-way pickup selector switch. Although not quite as nice as the single pickup Epiphone Newport it replaced, it was tougher, tonally more versatile, and less than half the price! Naturally it sold pretty well.
It was described as follows in the 1971 Pick Epiphone brochure:
The latest in modern appearance, the 1820 features a graceful modern cutaway design and a high gloss cherry red finish. Incorporates unusual quality, features, and performance at a very popular price. Features: thin modern cutaway design, high gloss cherry red finish. Slim, fast, low-action three-ply adjustable neck - Two powerful pickups with adjustable polepieces, pickup selector switch, rosewood fingerboard with pearl inlays, adjustable bridge, and rest, and foam rubber mute. Chrome plated machine heads and parts. 13 1/4" wide, 17 1/4" long, 1 3/8" thin; 30 1/2" scale, 20 frets.
The fact is, these were not bad instruments at all. Early Japanese instruments have a bad reputation, but this may say more about the people that bad mouth them than the guitars themselves. The Matsumoku plant was arguably producing the very best guitars imported from Japan at this time: the quality of woodwork, finish and hardware were all great. Some people report weak pickups, but this may relate more to the way the magnets are positioned below the coils, and the failure of the foam that holds them in position. It is true that the pickups are not up to 1960s Epiphone standards, but these aside, the ET-280 is a solid reliable bass.
The imported Epiphone guitars of late 1970 were based on existing models produced at the Matsumoku plant since the late 1960s. These were available from numerous dealers worldwide, re-badged, sometimes adapted slightly, but effectively the same guitars. For example, in the USA, Mersen rebranded Matsumoku guitars 'Univox', David Wexler used 'Conrad' and Maurice Lipsky 'Domino'. In the United Kingdom, Rosetti named their line 'Eros'. Not all models were available from all importers, but there are many more examples. Most of the late 1960s guitars were aimed at the lower end of the market, and although fully functional, lacked the extra appointments generally associated with even mid-priced guitars. For example, the headstock motifs were generally a plastic logo tacked onto the headstock. The Epiphone versions were certainly a step up. Some hardware (notably tuning keys) was upgraded, and the plastic logo replaced with a much nicer inlaid 'Epiphone'. Cherry finishes typically replaced Sunburst. The 1820 / ET-280 also changed from a single side headstock to a 2x2 style, in keeping with Epiphone tradition. Another example of this bass, also with a 2x2 headstock, was the Dorado 5988, introduced in 1973. Dorado was to Gretsch as Epiphone was to Gibson, and their version, coming towards the end of the Epiphone's production run is perhaps a little nicer still, with a tasty natural finish and height adjustable soapbar pickups.
Epiphone guitars and basses had been distributed in Britain by Rosetti since the 1960s, but they had also previously stocked their own line of Matsumoku Eros-branded guitars. The 1971 Rosetti catalog is very interesting in that it includes both the Eros (model 9526 - but now marked discontinued) and Epiphone (Epi 9526) versions of this bass. Note that both instruments use the same model codes. However, the Eros bass is priced at £37.50, whilst the Epiphone is priced £59.75.
The Epiphone ET-280 remained in the line until 1974.
