The Input Clipper
A very analog actionable hard clipper is inserted between the
A-preamplifier and the A-filterboard. It is useful to smash your tones,
squeeze dynamics and devastate the even-harmonics content of the
signal.
We did not put it there for any technical reasons, like compression,
limiting or something else: we put it only for fun. The idea is always the
same: morphing harmonics. In this case this process is made
before
all
the cutting circuitry, with a clear nasty purpose in mind.
In the VERTICE filterbank you have also other components which makes
a different-sounding brutal distortion, but
after
all the signal routing,
just before get out to see the outside world: it is the VCA circuitry and we
take care of it at
page 38.
The Overload Circuit
The Input Clipper is made by a simple active buffered circuit that make a true electric distortion caused
by a current overload of two transistors. We make them suffer. Obviously the A-preamplifier represents
the input level for this circuit, and the more you turn it clockwise the more it squares-off the sound, until
disrupting the low content and destroying all eventual lasting dynamics.
This circuit is simple but not stupid. It is active, which means it doesn't use the basic back-to-back diodes
configuration neither a biased-diode circuit, like the most passive distortion modules. That way is commonly
the noisy way. To reduce noise, which can be very present in this kind of circuitry, we made it active. That
means a different approach to the overload circuit giving improved flatness and square-sounding tones.
In addiction to that the presence of an IC buffer means a further noise floor dropped down and an increased
distortion at a given input level.
Be naughty and switch that button! :)
