BJFE  Pine Green Compressor

来自瑞典的手工发烧效果器。

 

4K绿压缩可以说是BJFE传统EQ Boost与3K压缩的结合体，压缩范围宽泛，手感影响非常明显。

 

无论在增加动态，缩减平衡动态方面，都有非常出色的表现。

PINE GREEN COMPRESSOR OWNER´S MANUAL

 

Thank you for choosing the Pine Green Compressor (PGC)

 

Short description:

 

This is a compressor pedal intended for use between a low level instrument such as an electric or acoustic guitar and an amplifier set for clean to moderate distortion.

 

Here are some typical settings and information on how to get the most out of the PGC.

 

The controls are:

 

COMP., which sets the amount of compression and sustain lower settings give mostly peak limiting, higher settings give more compression and less touch sensitive response and at maximum, output will be heavily compressed, while still retaining clarity at almost infinite sustain.

 

A good starting point for this control is a bit below centre (ten o’clock) with most guitars.

 

Gradually reduce Compression until effect is unhearable but noticeable when bypassed for best dynamic feel. Advance Compression if a limited sound is desired.

 

VOL. sets the balance between processed signal and non processed. A good starting point for this control is a bit below centre (ten o’clock) or a bit lower.

 

Input performance:

 

The unit has high input impedance presenting only a light load to the pickups, and the volume control on the guitar can be used as an auxiliary drive.

 

Output performance:

 

The output is designed to work into moderate to high impedance such as that of a guitar amplifier and most effect boxes and tape echoes.

 

Maximum load extends down to around 10K.

 

Power requirements:

 

The unit is designed to work from a 6F22 9V battery contained in the box (you gain access by removing the four bottom screws) CAUTION! Never operate the unit with its bottom removed or damage will most likely occur.

 

The current-draw is in the approximately 4,5 mA with the pilot LED lit, and 3,5 mA without.

 

PGC will however work down to 7 Volts.

 

If sound gets muddy or LED light dim it is time to change battery.

 

This is a compressor unit intended for use with electric or acoustic guitar, to limit attack, prolong sustain by increasing amplification factor as a plucked note decays, making signal more uniform.

 

Compression is powerful tool when recording and in live situations with acoustic guitar and steel guitar- properly set it can smooth out unintentional level changes for better audibility.

 

It has often been said that the best use of compressors is when you cannot hear them but miss them when they are turned off with electric guitar it is often used as an effect, by setting compression high enough to hear the signal being limited and decay being amplified.

 

Though compressed the tone is still in the attack only now attack is accentuated by a characteristic" chop". With compression weak parts of signal will be amplified and so a compressed signal will appear to have slightly more treble to it.

 

It is therefore common in compression design to cut some treble thereby noise is also reduced.

 

This technique is not used in the Pale Green design since the more filters you have in the chain the more phase distortion, and such filtering would be virtually impossible to make unhearable in all possible situations.

 

It was instead voted that there should be no filtering action except that needed to secure safety against radio interference and that the use of custom parts and design should ensure low noise with preserved treble.

 

These are the key features that are the basis of the Pale Green Compressor design:

 

• 1. Fast attack, slow release - the most used setting by guitarists ever. Response has been optimized for the parts used.

 

• 2. Wide range of compression: from light transient limiting to massive compression at almost endless sustain.

 

• 3. No treble loss, thus pedal can be used at various places in chain (Keep compression at lowest possible to achieve desired sound, to ensure lowest noise).

 

• 4. Low distortion and good overload characteristics.

 

• 5. Heavy duty design for reliability.

 

• 6. Battery monitor built in - when battery runs low LED-lights gets dim.

 

• 7. Low current draw for added battery-life.

 

• 8. Security: the unit must compile with standards set for this intended use.

 

• 9. Boost capability - at very low settings of compression unit can also be employed as a booster.

 

• 10. A nice colour: this one's Pale Green.

 

• 11. Complete bypass - something almost mandatory these days.

 

• 12. Original Circuit.
