Documents - the Vox AC30/4 and Vox AC30/6

mid 1960 and 1961

Below, a selection of documents relevant to the AC30 in the second half of 1960 and 1961 - some part of a large batch sent by JMI in 1961 to an enquirer who lived in Hull.

The principal change outlined is the move to the new six-input AC30 - the AC30/6. An AC30/4 bought before 1st October 1961 could be had at the old price of 95 guineas (£99 5s). A new AC30/6 Twin would, as a special introduction, be 100 guineas (£105). The price thereafter: 105 guineas (£105 5s).

In 1962 the price of the AC30N went up to 115 guineas (£105 15s); the AC30B was 120 gns (£106).

A JMI pricelist from mid 1960 giving the price of the single speaker AC/30 and the new TV Front twin (printed in "Vintage Guitar" magazine, May 1993). This marries up nicely with the prices given in "Accordion Times", May 1960.

Pricelist, no date, but doubtless mid 1960 given the correspondence with the advert placed in the "Accordion Times" below.

Detail from the advert below.

"Accordion Times", May 1960. The AC1/15 at 65 gns, the AC/30 at 79 gns. The amplifier at 100 gns is the new AC30/4 twin - .

It will be necessary at some point soon to split the in two: one for the AC2/30 and another for the single-speaker AC/30.

Advert from the first edition of Shirley Douglas's "Easy Guide to Rhythm and Blues for Bass Guitar", mid to late 1960, advertising JMI's new franchise of Fender guitars, and illustrating an AC15.

Note the "VOX" logo and the "15" in small lower left on the front of the amp. The picture used in the Shirley Douglas advert had certainly been printed before - but without a secondary logo - so the image was probably specially mocked-up for reprinting in 1960.

Shirley Douglas, "Easy Guide to Rhythm and Blues for Bass". The amp quoted at 75 guineas is the single speaker AC/30.

Detail of the front of the amplifier. No AC15 is known with an emblem of this sort.

"Melody Maker" magazine, 9th July, 1960. Shirley Douglas and Chas McDevitt.

"Melody Maker" magazine, 30th July, 1960. Shirley Douglas and Chas McDevitt with the *new" Vox amplifiers. The newness in question was the advent of the AC30/6 and doubtless the new split front cabinets.

Also "Melody Maker", 30th July, 1960 - "Paul's Music Studio". Paul was in fact Paul Jennings, son of Tom, and manager of the shop at 88 Broadway, Bexleyheath - better known as "Musicland".

"Banjo, Mandolin and Guitar" magazine, August, 1960. There is also an advert in the September issue.

"Melody Maker" magazine, 19th November, 1960. The AC30/6 is 89 guineas; the AC AC30/4 is 85 gns. There is also an AC30/4 Bass model at 89 gns.


"Melody Maker" magazine, 7th January, 1961. The AC30/6 is now 95 guineas. The AC30/4 Normal and Bass remain at 85gns and 89gns respectively.

An illustration of changes slipped into various iterations of JMI literature. Below, one side of a fold-out brochure printed for "Musicland", effectively a second Jennings shop, in early 1961, and a detail. The only amp illustrated is the AC2. Others however are listed.

The third pic. is a different version of the same brochure - note the AC2 again - but with a variant list of amps.

Above, the brochure for "Musicland" and detail.

The image above is a digital composite. The brochure in reality takes the same form as the "Musicland" printing. Note in this version, however, the inclusion (original) of the AC30/6 TWIN.

"Melody Maker" magazine, 20th May, 1961, the AC30 in view said to be "New" - re-stated in the first line of the text: "new series amplifiers" - corresponding to the "List of Changes" noted on the circuit diagram, 8th May 1961.

"Melody Maker" magazine, 16th September, 1961. The AC30/4 is still listed.

"Melody Maker" magazine, 23rd September, 1961. The AC30/6 alone listed - no mention of the AC30/4.

JMI reply to the original response for brochures and pricelists.

JMI Announcement, October 1961 - the end of the AC30/4 and the arrival of the AC30 Super Twin.

Pricelist to accompany the JMI Announcement, above. The new AC30/6 is 100 guineas.

"Melody Maker" magazine, 28th October, 1961. The first mention of the AC30 Super Twin - the "Super Twin de Luxe" = Super Twin I - in these adverts.

The next JMI pricelist, still October 1961 (note the "10/61" in the lower right hand corner of the reverse). The new AC30/6 is £105 (= 100 guineas); the Super Twin I is £131 5 shillings (= 125 guineas).

Note that Top Boost is signalled as being a feature in the second paragraph on the left - and probably repeated in the third: "stereophonic tone controls", a fairly loose use of the word "stereophonic". Note the full valance fronts of the speaker cabinets and the black vinyl (as seen in the publicity shot of Shane Fenton and The Fentones).
