INTRODUCTION
With the original SlideRIG, our goal was to reproduce the slide guitar tones first heard on Little Feat’s classic album "Di xi e
Chicken". The ton e is clean and transparent, with an almost infinite shimmeri n g sustain. For many, this represents the u l ti ma te
in slide tone.
In the studio, the Little Feat tone was achieved by daisy-chaining two Urei 1176 FET compressor channels, one after the other .
The 1176 has a fast response, unique character and smooth compression profile. Chaining the compressor sections allows this
character to be retained, while vastl y increasing the amount of compression. This high deg ree of compression is generall y referred
to as "limiting" as the signal is maintained at a consistent level.
Our 1176-inspired Cali76 circuit forms the back bon e of the SlideRig, with two identical Cali76 blocks being uti l i s ed in a true, dual-
chained, topology. We included a studio-grade 1960s-style discrete preamp, to work as an electronic interface between your guitar
and the compressor. The preamp provides gain and also creates the optimum conditions for signal transfer.
In designing the Compact Series pedals, Origin Effects has gone to painstaking lengths to pres er ve the bu i l d qual i ty an d son i c
integrity of the original Cali76 and SlideRIG circuits, even improving on them where possible.
The further reduction in size has been achieved by using a mixture of traditional through-hole and SMD components, spread
across a pair of densely populated, stacked boards. The signal path utilises film and tantalum capacitors, carefully chosen low-
noise transistors an d rugged MELF resistors (ess en ti al l y traditional through-hole resistors without the leads), which offer low-
noise performance and rock-solid reliability.
One of the reasons why the original Origin pedals sound so good is that they deliver true FET compression, with a fast yet hi gh l y
musical response that is a world away from the brutal and unforgiving sound of traditional VCA compressor p edal designs. The
new Compact Series pedals stay true to Origin's design philosophy with absolutely no opamps or VCAs used in the signal path.
The new pedals are powered by mains adaptor onl y. Dispens i ng with the usual internal 9V battery option allows more space
inside the enclosure for high-quality circuitry, while also supporting the high-current circuit design that is the key to thes e pedals'
astonishingly low noise levels.
