The de-cerealiser was not a processor of any description, but a device 
for allowing the position of a click to be accurately marked on the 
tape, so that the oxide layer could be partially scraped off at that 
exact point. Accuracy was of the essence here, as the effect of scraping 
to one side or other of the click merely accentuated it. Hit it 
squarely, however, and it sank into the surrounding surface noise most 
satisfactorily. The violin bow analogy comes from the technique of 
operation, which was to grip the tape in the device and move it in a 
series of tiny jerks against the pressure of a finger or thumb. The head 
output was fed to a dynamic speaker, and a change in character of the 
sound from the head listened for. When, as John put it, the noise 
appeared across the face of the speaker as opposed to the interior, 
there was the click. A quick blip of the marker and the click was 
located. Out of the device, scrape off about half the depth of the oxide 
at that point, and away went the click.

If you think I've been at the head cleaning fluid you have my sympathy, 
but that is how it worked, and it worked well. I built my own under 
John's direction and learned how to use it. It was a good tool for the 
time, better than anything else for removing the residual from Packburn 
or Mousetrap. It was only clearly bettered when the likes of Cedar 
manual declick became available. The process was laborious, and I never 
came close to John's speed, but it was certainly effective. I still  
have mine somewhere...
