Effect Information

An interesting story edited from the original eBay listing:

“From
here to obscurity — or the story of the Zonk set. The Zonk Machine —
and its partner in tone — the matching Treble Booster were made in
Leeds, England, 1967 to 1969, by John Hornby Skewes Ltd. That’s our best
information on origin.”

“How many effects come to mind where a company issues a
second pedal to boost the performance of the original effect? Let’s just say it’s
pretty unusual — but the matching Treble Booster adds a lot to the Zonk Machine.”

“As a matter of fact — twisting the Swell control without the Treble
Booster is nearly a waste of time. Maybe the HS engineers put the
Booster in a separate box to improve signal to noise ratio. Maybe they
had a load of Zonkers made when they discovered the “Swell” function and couldn’t live without it — who knows?

“The Treble Booster not only add
highs, but enables a significant expansion of the Swell function. It
makes all the difference in sound. This effect has other mysteries too. The tone
is somewhat similar to a Foxx Tone Machine, without the octave. Is it a
coincidence, or did one borrow from the other?”


I have no idea whether any of this is true but makes for an interesting read.
