Vox AC30 cabinets - small single letter logos
1964 - 1966
AC30 Super Reverb Twin serial number 2741.
Small V O X logos, single letters. In terms of dateable occurences, they first appear in late July 1964 on the AC100s issued to John and George of The Beatles - the amps said to have been ready on 17th, seen in public for the first time on 28th. Copies of the reports can be found on this page.
Stockholm, July 1964.
The only other AC100s fitted out in this way were retained by JMI for loan / demonstration.
The letters of early examples tend to be extremely widely spaced. Models also given small single-letter logos from time to time during the course of 1964 (and in later years) were:
the AC50: the first instances probably among serial numbers in the 1180s, 1207 certain, pictures on this page.
the AC30 Super Twin amplifier section: earliest instances currently known, insofar as serial numbers go, being numbers 2714 (plain Super Twin) and 2741 (a Super Reverb Twin). The box of serial number 2763 is probably from some later amp. By far the greatest concentration of examples occurs in the serial number range 3200 to 4200.
the AC4: serial number 4870 the only example encountered definitively so far.
Whether the letters always came from the supplier with lugs at back, as in the case of the "O" pictured below, is not known. The suspicion is that sometimes they were removed at Dartford Road, the plastic cemented directly to the grille cloth.
"Small "O". Other small "O"s (no longer attached to amps) appear to have had their lugs neatly removed.
Below, a shot of the remaining letters on a Vox AC100 from the late summer of 1965 (circuit conforming to the "100W Amplifier" sheet). The "X" in this instance clearly had two lugs, one top left, one lower right. Other examples of the small single "X" have a single lug at the intersection of the arms, perhaps having been cut away from a small single-piece logo which had lugs only for the "V" and "X".
Single-letter logos are uncommon on AC100s. At present just seven are known, at least two of which will probably not emerge from their hiding place for some time yet (but they are known from photos).
AC100, serial number somewhere in the 600s (plate gone).
The other side of the baffle of the AC100 with a logo composed of small single letters pictured below. The "V" has three lugs, the "O" two, and the "X" two. Please forgive the rough and ready outlines.
