Analog Man Bi-CompROSSor Manual

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 battery or 9V DC center negative adaptor (not AC! This will blow up the pedal!). 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 4mA when off.

SUSTAIN KNOB

higher it is set, the louder the volume will be swelled and the more the attack will be compressed. Starting in
2003 we are using a Reverse Log potentiometer for the sustain knob just like the original Ross and Dynacomp
pedals. This allows easier control and setting to the same position that is used on those pedals.

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. Attack trim pot inside or optional external ATTACK knob
5. Power adaptor jack (Boss style) or internal battery
6. 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 compression. The
