The Hagstrom Concord bass, also known as the Viking bass in the UK (alluding to it's Swedish origin), was available from 1965-1971. It was a companion instrument to the Viking electric acoustic guitar. According to shipping figures, the standard, C1 Concord bass was produced in just 3 batches; making this one of 2749 instruments. There was a further batch (150 instruments) of the C2 Concord De Luxe. See the Hagstrom Concord shipping figures.
The double-cutaway Concord bass was naturally inspired by such instruments as the Gibson EB2 and Epiphone Rivoli; and although it shared the same body style and short (30 1/2" scale) there were several major differences between these models and the Concord: the lack of set neck on the latter, the single coil rather than humbucking pickups and the central maple block on the former. The completely hollow body does make this bass a little more prone to feedback than those with the internal maple block, but also reduces the weight significantly. At a shade less than 3 kg, this example is actually very light indeed; lighter than many guitars in fact.
This bass, in Cherry Red finish, has a birch front, back, sides and neck. It is from the third and final batch of Hagstrom Concord (C1) basses and most likely dates from 1967, or very early 1968. The 1968 Hagstrom catalogue gives it a list price of $285
It is a great sounding bass, the completely hollow-body giving a nice woody tone. It does feedback a little; but actually enough to be useful when needed. - the two clips below are the guitar through two of my favourite vintage tube amplifiers: first an old portaflex Ampeg B15; secondly an early 70s silverface Fender Bassman with 4x12 cabinet. There are numerous other clips of this guitar here.
All clips are recorded with the amp mic'd with a Shure SM57 microphone.
