Gibson EB3 publicity, and pricing information

[1] June '61 letter to dealers announces the new 'Les Paul' (SG) basses, prices are $285 and $195 for the EB3 and EB0 respectively
[2] The first pricelist to feature the EB3 had just three basses - EB0 - $210, EB3 - $310 and EB6 - $325
[3] In mid 1965 the price of the EB3 dropped slightly, with this price being held for a further three years. Sales had been relatively weak up to this point. Around this time the control cavity route of the EB3 and EB0 were redesigned to be uniform - perhaps this change reduced production costs enough to allow this price cut
[4] Sales in 1974 had dropped to a third of the 1973 values - initiating this price drop, although sales were still dropping, forcing another drop [5] later that year
[6] In late 1975 and 1976, white EB3s were priced at $30 above cherry instruments
