Vox "diving boot" volume pedals are extremely scarce these days, many presumably having been junked over the decades due to weight, general unwieldiness, and so on. Designed in late 1957, they remained in the JMI catalogue through to early 1963 and must have sold in reasonable numbers. The dark grey/black pedal below is serial number 4504, the sequence probably having been kicked off at 4000. The very earliest pedals had silver hammerite bodies and treadles, or black bodies and silver treadles.

In terms of dimensions: the pedals are 13 1/2" long and 4 3/4" wide at the widest point. When the treadle is depressed at rear to its greatest extent, the top at front is 5" above floor level. The walls of the base are 1/4" thick, those of the treadle 5/16". The central base plate is 3/16" thick. The "buttresses" inside the base stop short of its bottom edge by 3/32". It may be that rubber strips were glued to these.

On the black pedal below, the output jack socket at front is a Bulgin J6.

Thanks to Martin, a shot of an early "diving boot" (superimposed on a plain background) that once belonged to Dick Denney. Its body is silver hammerite, the ridges on the rubber pads on the treadle aligned across the width. as in the early advertising pictures.

Pedals of this type (in terms of external appearance) were certainly issued with the earliest Vox Continental organs and were probably available for at least a year or more before that - either for use with guitar, or one of the portable organs that Jennings supplied.

The pedal below, serial number 4504, was purchased in the 1970s from an organist.

The top at front is 5" above the floor.

13 1/2" long and 4 3/4" wide at the widest point.

The "buttresses" around the inside stop short of the top by 3/32". None has a fixing hole, however.
