April 1967 pricelist.

The Russell Hotel Music Fair, August 1967. The large cabinet on the left with the angled front may be a first design for the Gyrotone IV. The amp sitting on top was later put into production by Jennings Electronic Industries, not Vox. See the examples on this page.



Above, the band "Time Cycle" with an early split-front Gyrotone III. Note the two twelve inch speakers in the lower section of the unit. For later Gyrotone IIIs see the foot of this page.



Pages from 1970 and 1972 (Melody Maker) advertising the Gyrotone II and III. For the Midas amplifier mentioned in the page from the Melody Maker, see here.





GYROTONE I

Produced first by JMI, then by VSEL and VSL. Serial numbers for JMI units began at 5001. Vox Sound Ltd serial numbers began at 001. JMI made 150 or more - see the Gyrotone Is immediately below.


NEW

Sold on ebay uk in early 2017. An early JMI Gyrotone 1. Good overall condition and complete with its cover (identical to the one pictured below).




NEW

A JMI unit, serial number 5155. Perhaps the original footswitch - as for the solid state bass amps - but corroboration needed.




Vox Sound Ltd, serial number 047. By 1969 the Gyrotone I had been phased out. Adverts only mention and illustrate IIs and IIIs.




Quick snaps of a loose Gyrotone Mk 1 cover, no gyrotone to go with it at the moment. It is 18" tall and measures (round the hem) 21" x 25 1/2". There are openings for handles low down on both sides.

GYROTONE II

An example with an angled front. Note the gold string - ie. earlier than the one in "square-format" below.



The Jennings version of the Gyrotone II.




Another example of the Jennings version but with a Vox badge.





A further example of a Jennings Gyrotone (re-grilled with Vox cloth).



A later flat-fronted Gyrotone II - the cab not unlike Foundation Bass cabs, with an overhanging lip. Silver string.






GYROTONE III

NEW

Vox Sound Ltd, serial number 068.




NEW

Sold on ebay.uk in early 2017. A nice Gyrotone III, Vox Sound Ltd, serial number 069. Note that the speaker has a VSEL sticker.
