BJFE Little Green Wonder  4K

Little green wonder（LGW）是TS类过载音色，是screamer风格单块的升级（发布于2003年1月8日）。

LGW提供一种相对于比较平滑简单的过载，这种过载能使clean音色更加平滑顺畅，或者也能提高失真音色的crunch增益。

最初的75个LGW安装的是National Semiconductor（美国国家半导体）的LF353芯片；

2005年之后LGW安装的则是Texas Instruments（德州仪器）的TLC272芯片。

相比之下，LF353芯片在headroom上有较好的表现，但不能在8V以下的低电压下工作；

而TLC272芯片却使LGW在低电压下有不错的表现。TLC272芯片同样轻微的在失真方面产生了更多地复杂性。

LGW是Mad Professor Little Green Wonder的原型机。

在作为boost功能的同时具备了BJFE动态的强项，弥补了以往TS类音色缺失动态的不足，不论您是节奏还是solo，LGW都能自如应对。

4k版本在原有3k版本上增加了高频调节，音色更为灵活多变。

Updated tube screamer style . The LGW provides a smooth distortion, which is fine for smooth use on a clean sound or for enhancing a crunchy distorted sound.  This LGW is socketed to experiment with different chips, the LF353 is preferred if you require more headroom, the TLC272 also provides slightly more complexity in distortion.

Premium quality classic blues/rock pedal that works very well with complex overdriven amp sound. This pedals is now offered as lower priced pcb-model or hand wired pedal.

It's a low compression, high headroom overdrive with high output, and it has a Body knob for adjusting low-mid content and treble.

The LGW was made to be a stackable overdrive that could go anywhere in the pedal chain and the compression normally associated with this type of circuit is reduced same as several distortion mechanisms.

This pedal will work very well with amps and other pedals that have a lot of complexity or compression, a situation that not all pedals work well.

LGW makes a great building block to sound yet it works standalone and especially with humbuckers where normally this type of circuit would not work satisfactory, much due to bass loss and sometimes separated sounds (where transients feed through and a cloud of distortion follows beneath.

Body control gives access to medium midhump at center position and allows treble boost at cw rotation and low mid/treble boost a ccw position and so unit also can provide distortion albeit a smooth type. LGW can be used as an overdrive to already distorting amplifiers or pedals downstream, as well as function as a filter when feed with fuzz pedals that may be rough on some amplifiers and can also be used as light overdrive for just breaking up sounds.

As designer Bjorn Juhl put it:

"Whereas Little Green Wonder is a TS-style pedal, but one for those who don't generally like TS-style pedals.

Big difference between these two pedals would be headroom, distortion style and distortion depth and treble response, output level, function of tone knob, color, symbol.... they do share a common layout of mechanical components."
