15th March

Dynamic Bass serial number 1011. Thanks to Sergio for the pictures. More to follow.

12th March

Above, a well-used but still-playable copy of the flexi disk produced by Thomas Organ to promote the new Vox Wah-Wah pedal in February 1967. Batches of the disk were evidently sent to Jennings for the promotion of its new pedal, released a couple of months after the American one.

See the entry below for 27th January for some more Thomas Organ advertising.

18th February

Defiant serial number 2085, "Vox Sound Equipment Limited", late 1968 or early 1969, complete with its cab and footswitch. Thanks to Romu for the pictures. One of the capacitors is marked "February 1968".

11th February

The entry below for 25th November notes the addition of an . A couple of new photos indicate that is definitely early (and not just "earlyish").

The speaker cab is stamped as an ST30 (Super-Twin 30) rather than "Conqueror":

and the surviving 2N3055 has a date code beginning "6" - 1966, possibly "6E" or "6G":

Image enlarged beyond its natural size.

9th February

The entry below has been updated with further images of the Jennings version of the brochure.

8th February

Below, the Thomas Organ brochure from 1966 setting out the rationale for transistors. This was taken up in 1967 by Jennings and issued with a slightly different cover and other modifications.

The four pictures above, the Thomas Organ brochure

The cover of the Jennings brochure. Notice that the amplifier sections do not have the sloping sides depicted in the Thomas version.

Below, pages from the JMI solid state brochure, printed in black and white in the "Vox Story", ed. Denney and Petersen. The text provided in the American version has been enlarged upon considerably.

3rd February

The nicest Dynamic Bass to have come to light so far - serial number 1068, the speaker cabinet still with its original cover. Thanks to Matthew for details and pictures. The amp is . Below, the cover, with its cut-outs at back for the chrome amp support:

The cut-outs for the chrome support are reinforced with black leather surrounds (as the handle opening of amp covers are) to prevent tearing.

28th January

Dynamic Bass serial number 2049 - "Vox Sound Equipment Limited", early 1969 - .

27th January (2)

Vox Teenbeat Magazine, volume II, no. 2, early 1967

"Billboard" magazine, 17th December, 1966. A picture of T. Warren Hampton, to whom applications for details of the new Thomas Organ Wah-Wah pedal were sent - see the entry below.

27th January

A Vox grey Wah from late 1967 / early 1968 - serial number 6382 - is currently on (no affiliation). Around 2,000 of these pedals were made by Jennings. See this page.

Below, early advertising for the Thomas Organ wah-wah pedal, which preceded the English one by a couple of months:

"Vox Teenbeat" magazine, volume II, no. 2 - not dated, but evidently from early 1967. The Stones tour of Europe "this year" - Hamburg, Berlin, Essen...Zurich, Athens, is mentioned. The tour in question took place in late March / April '67. And The Monkees are said to have scheduled two performances in London - which took place in July '67. Lower left in the advert, "Vox Ltd and Wah Wah Girls" - what a name.

From the same magazine. Mr T. Warren Hampton was the Wah-Wah man at Sepulveda - see the form below. Note the offer of the free record. There were also commercials on the radio - YouTube clip below.

The form.

26th January

Vox Foundation Bass serial number 2836. A great set, currently in Belgium. The amp was probably made in late 1972 / early 1973, one of the last of the line.

23rd January (2)

Dynamic Bass serial number 2094 - "Vox Sound Equipment Limited" - .

23rd January

Traveller serial number 1218 - "Amplifier" rather than "Vox Amplifier" on the plate:

22nd January

Three JMI Conquerors from late 1967 / early 1968. They straddle the period during which logos came to have "Solid State" in smaller letters under "VOX":

vox conqueror 1459

Conqueror, , said to be serial number 1459. The logos, however, do not have "Solid State". Perhaps correct.

vox conqueror 1425
vox conqueror 1425

Conqueror serial number 1425. "Solid State" in the logo of the cab but not the amp. The amp is registered .

vox conqueror 1968

"Solid State" in the logo of the amp, so a serial number somewhere above 1420. A good set, complete with footswitch.

21st January

A Defiant from 1972 . The back panels of amp and cab do not survive; the two are nonetheless in reasonable order.


23rd December

Vox Sound Equipment Limited microphones, the VL1, VL2 and VL3

A new page begun on . These originally came into the Vox catalogue in 1966.

16th December

On the 3rd January 1969, Les Hills, who had designed the electronics of the T60 amplifier and various organs for Jennings, lodged a patent application on behalf of "Vox Sound Equipment Limited" for a polyphonic keyboard circuit. The designers of the circuit were Hills himself, Rodney Angell and Kenneth McDonnell, all VSEL employees.

The application is archived on the European patents website , aggregated from a German and Dutch source.

The cover page of the sixteen page German outline of the circuit. A translation of the whole will be made available in due course.

Second page.

The last page of the German document, illustrating some key points in the circuit and wave form product.

Five Jennings Musical Industries patent applications, 1955-1963 - inventions of Les Hills and Derek Underdown for organ and guitar elements - .

A further two are: (Les Hills, 1953); and (Les Hills and Derek Underdown, 1951).

Use the menu at the side of those patent pages to find the document, drawings and so on. Various dates are given - of submission, approval, and so on.

15th December (2)

Just to note in passing that in 1972, towards the end of "Vox Sound Limited", horizontal amp logos were sometimes used for Defiant and Super Foundation Bass cabinets.

Vox Sound Limited Defiant amplifier and speaker cabinet

Conquerors and Dynamic Basses had been phased out by the time the amps above were produced. So far as one can tell, however, Supreme speaker cabinets were always given centrally-placed trapezoidal logos - so too Foundation Bass cabs.

Dallas Arbiter and Rose Morris gave a good number of Foundation Bass cabs (the FB118) old-style Vox "letter" logos placed top left. One sometimes find these paired with late VSL Foundation Bass amps - perhaps old stock being sold off.

15th December

Just to note that Defiant no. 2784, late "Vox Sound Limited", is currently on (no affiliation). The mains transformer is noted as being defective. The original green label Goodmans Power Range drivers are still in place in the speaker cabinet.

11th December

A nice "Vox Sound Limited" Tonebender from 1971-1972 just sold on ebay. Made for Vox by Sola Sound. The underside notes the Hastings address.

Below an example of the "Hastings Wah" with the same blue and gold logo. The peculiar hole in the foot treadle for the switch was a short-lived experiment by Sola Sound. It's also found on Vox and Sola badged Wow Fuzz pedals.

30th November

Two things to note: the February 1969 pricelist supported four brochures, not three as stated below (25 November, 2). The fourth illustrated microphones and PA amplifiers.

The Vox "VL" microphones were produced by Reslo - versions of the Reslo UD.1. Vox also sold Reslo ribbon mics (listed as Reslos in its catalogues - ). In early days a small "VOX" logo was added to the throat of the mics.

29th November

A "Vox Sound Equipment Limited" VL2 omni-directional mic, complete with cable and pouch. Further pictures to follow.

The VL2 in the pricelist of 1969.

Below a "Vox Sound Equipment Limited" VL3 uni-directional microphone with cable:

26th November

The Guardian, 26th August, 1966, reporting on the British Musical Instrument Industries Trade Fair at the Russell Hotel (21st - 25th August). Interesting to note that sizeable orders were placed for the new range of "transistorised amplifiers". These, however, did not appear on the market until March 1967.

"Beat Instrumental" magazine, October 1966 - the new Conqueror.

A growing series of pages on Vox showings at Trade Fairs in the mid and later sixties is available on the .

25th November (2)

February 1969

Vox Sound Equipment Limited pricelist, February 1969, front and rear covers

The "Vox Sound Equipment Limited" was issued in conjunction with three brochures - one each for amps, organs and guitars. The prices of amps in the pricelist were noted on the amp brochure below - probably soon after it had been issued.

The prices cited represent an increase on those quoted in late 1968 - see the note in . The market had become extremely tough for Vox in the last years of the sixties.

Supreme , the lowest number to date (as Supremes go) with "Solid State" in the logo. Thanks to Kjell for the pictures.

24th November (2)

The full text of the 1969 pricelist has now been posted: the , and the .

24th November

JMI pricelist from April 1967 (the earliest to give prices for the new solid state amps) and Vox Sound Equipment Limited from February 1969. The latter marks a radical contraction of the range, though certain things not in the list were evidently still being sold. The VSEL list is physically a trifle larger than the earlier one.

22nd November

Foundation Bass serial number 2427, late "Vox Sound Equipment Limited", registered . A series of updates to follow this weekend.

17th November

"Vox Sound Limited" - an advert in "Melody Maker" magazine, 23rd October, 1971, for the showroom at 9 Gees Court. See for the various moves of office/showroom and factory in 1971. Unfortunately the mains power consumption of the guitar and bass amps is given rather than the music output - the Defiant and Foundation Bass are 50W amps; 100W (noted on the serial number plate) is what they consume from the mains.

11th November

A great new Supreme has just come to light, "Vox Sound Equipment Limited" serial number 2043, complete with covers, tilt-back stand, and footswitch. Thanks to Dario for the pictures.

8th November

A nice Conqueror and cab (with fittings) currently on The latter also has its original Celestion T1088s.

30th October

"Midland Beat" newspaper ran from 1964 to 1967, charting the music scene, in the main, at a local level in the midlands of England. From '64-67 there are no Jennings adverts - some pictures of groups with Vox amplifiers - but no great sales push. The Midlands were the preserve of Marshall and Park (some great early ads for those companies, especially Marshall). Then in 1967, with the advent of the solid state line, two huge Jennings ads appear:

March 1967. The illustrations are of the pre-production amps, the footswitch socket further over to the left and indicator lamps on top of the control panel. Some key comments from Tom Jennings - development of the range took some 80,000 man hours; Colin Barrett, the rep. for JMI, has been besieged with requests for the new range when travelling abroad; the Vox stand at Frankfurt Fair, one of the most important events in the calendar for Jennings, is likely to generate great interest; also on show, the new Gyrotone range.

Detail from above. The Super Foundation Bass cab is in its "production" form. In February 1967 it was illustrated in a form that was considerably wider.

April 1967.

25th October

The "Daily Express", 1st February, 1975. The end of Dallas, which had taken on the production of a small selection of Vox items, and another end for Vox.

JMI wahs first came to market in Spring 1967. There is not a shred of evidence at present to show that any were produced in 1966.

30th September (2)

"Vox Sound Equipment Limited" Conqueror serial number 2377, distributed in Denmark by "Alfred Christensen". Thanks to Erik for the pictures.

Christensen also distributed two other Conquerors - no. 2271 and one with no number - Defiant no. 2258 - and a Supreme with a number probably .

For the Danish market, VSEL designated the Dynamic Bass "C2", Conqueror "C1", Foundation Bass "B2", Defiant "B1", Super Foundation Bass "A2", and Supreme "A1".

The main agent in Denmark was "European Musik Import A/S. Kirke Vaerlosevej 261, Lille Vaerlose, a little to the north of Copenhagen. See .

The paragraphs below, from

Midt i 1960erne blev MAX produkterne distribueret til det danske marked af en virksomhed i Lille Værløse (forstad til København) med navnet Europæisk Musik Import A/S. Dele af fabrikationen foregik i Lille Værløse, andre dele muligvis (der er delte meninger om sagen) i England. Indehaveren af det senere SuperSound, den navnkundige hr. Larsson, der på samme tid boede i Lille Værløse, var hjernen bag E.M.I. (ikke at forveksle med det engelske pladeselskab med samme initialer).

Larsson, som importerede Vox, havde fundet ud af, at han kunne undgå diverse skatter og afgifter på komponenter (rør, trafoer m.m.) ved at importere løsdelene separat og derefter samle dem her i landet. Det gav ideen til et nyt navn indenfor dansk produktion af forstærkere: MAX.


In the mid-1960s, MAX products [amplifiers, speakers, and so on] were distributed to the Danish market by a company in Lille Værløse (suburb of Copenhagen) called European Music Import A / S. Parts of fabrication took place in Lille Værløse, other parts possibly (there are shared opinions on the matter) in England. The proprietor of the company that was to become "SuperSound", the renowned Mr. Larsson, who lived at Lille Værløse at the same time, was the brain behind E.M.I. (not to be confused with the English record label with the same initials).

Larsson, who imported Vox, had found out that he could avoid various taxes and duties on components (pipes, trams, etc.) by importing the loose parts separately and then assembling them here in the country. It gave the idea of ​​a new name in Danish production of amplifiers: MAX.

30th September

A Goodmans speaker brochure from the 1970s (to judge by the graphics), probably from a year or two after the end of "Vox Sound Limited" (1973). Note the different varieties of the Audiom 12-P. The particular type was only marked on later Goodmans red labels.

21st September

"Melody Maker" magazine, 8th February, 1969. In a section on the Frankfurt Music Fair, a page by "Vox Sound Equipment Limited" on solid state amps. The standby circuit is still in place. Controls, circuit boards, and other elements in the drawings are numbered and described in the accompanying text. Click as ever for larger images.

Given that many will only have seen the Vox solid state range in catalogues, shops, and pictures, the piece is likely to have furnished useful info - clearly and concisely.

Just for interest, a good-ish large detail of John Lennon's Vox Conqueror on the stage of the Savoy Theatre during the filming of the "Hello Goodbye" video. Slightly indistict though the runner on the front may be, I'll eat my hat if it says "Defiant" rather than "Conqueror".

A detail of the same amp showing its two metal vents. Defiants had four.
