Analog Man CompROSSor Manual

BASIC information:

This pedal is quite similar to an MXR dynacomp but Ross improved the circuit to make the sustain
more solid- less wavering and seasick sounding. It uses NOS (new old stock) 2SC1849 Matsushita
transistors which were used in the original ROSS compressor and early script logo MXR
dynacomps. We use higher quality capacitors than the original, for improved sound. The circuit
board is double-sided with GROUND PLANES everywhere possible to minimize noise. This is
important as any compressor amplifies ambient noise when you play lightly or stop playing, as they
go to maximum gain. Any noise from your pickups will be brought up when you stop playing, so if
you need complete silence it is best to turn off the compressor when you stop.

JACKS:

Right is input, left output. Battery is disconnected when input cord removed. Always
remove input cord when not being used as battery will drain even when off.

POWER

: 9V Alkaline internal battery or 9V adaptor. Boss PSA, Ibanez, or Dunlop adaptors will
work fine. Voodoo labs or other high quality power supplies are recommended for best sound. The
effect draws about 10mA when ON and under 4 mA when off.

SUSTAIN KNOB

compression. The higher it is set, the louder the volume will be swelled and the more the attack will
be compressed. Note that I am using a linear pot for the sustain knob so the position of the pot will
have to be set higher to get the same amount of sustain as an original Ross or Dynacomp. All the
way up they are the same, but the taper is different. For example, half way up (12:00) on an original
Ross is more like 2:00 on my compROSSor.

LEVEL KNOB:

Sets the volume, can be used to boost the signal somewhat to drive an amp
further into distortion.
This product is based on an improved version of the Ross
compressor. Here are the basic specifications:
1. True Bypass
2. 3PDT stomp switch
3. Status LED
4. Power adaptor jack (Boss style) or internal battery
5. Re'an UK made high quality input and output jacks to
isolate mechanical noise.
: Turning up the SUSTAIN knob sets the amount of sustain and
