MAD PROFESSOR - FOREST GREEN COMPRESSOR - OWNER’S MANUAL

Thank you for buying the

fi nest Compressor/Sustainer
for guitar and bass use.

FOREST GRE EN COMPRESSOR (FGC)

is designed to meet the highest stan­dards of guitar and bass compression.
There is extremely low noise throughout
the range and a high overload margin,
which allows also a wide dynamic input
range at minimum distortion and noise.

FGC is equipped with a special tone control to
fi ne-tune the compressed sound for most transpar­ent tone and effect.

The pedal has a switchable compressor and sus­tainer mode. In Sustain mode you can get a very
dynamic, touch sensitive tone with a long sustain.
Here the attack is not lost, making the pedal suit­able even for blues players and works great with
slide playing.

The controls are:

• LEVEL: In Compressor mode adjusts the
overal volume and the FGC can be used even
as a booster. In Sustain mode the Level no
longer adjusts total output but the level of the
sustained part.

• COMPR.: Sets the amount of compression
and sustain. Lower settings give mostly peak
limiting, higher settings more compression and
less touch sensitive response. At maximum the
output will be heavily compressed, while still
retaining clarity at almost infi nite sustain.
A good starting point for this control is a bit
below centre (ten o’clock) with most guitars.

• TONE: Tone control on FGC is designed to fi ne­ tune the compressed sound for most transparent
tone and effect:
Adjust CCW for full range compression and set
at noon for tighter sound with a little less bottom
end and turn fully CW to slightly reduce upper
treble.

• COMPRE SSOR/SUSTAIN SWICH: Attack
and decay times are carefully fi ne-tuned and
internally set for swift attack and slow decay.
