Analog Alien Joe Walsh Double Classic Comp/OD - Used  From Other

COMPRESSOR

The Compressor in the JWDC allows you to control the dynamic range of your instrument. Unlike most stomp box compressors, the compressor in the JWDC has a very natural and musical sound – much like professional rack mounted compressors found in professional studios.

Sensitivity – This control is similar to a threshold control that is found on professional studio compressors. It allows you to make adjustments to the signal level at the input stage of the unit. This control comes in very handy if you are using a bass or a guitar with active pickups. Active pickups tend to have a hotter output than passive pickups. By adjusting the sensitivity properly the output level of your instrument can be controlled, so as not to distort the input of the compressor. The opposite is true if the bass or guitar has passive or low output pickups. Raising the sensitivity control increases the input level, providing a stronger input signal which the compressor needs in order to work properly.

Ratio – This knob allows you to set the compression ratio. The range is adjustable from 2:1 to 10:1. The more you turn this knob up (clockwise) the higher the compression ratio. There is also a soft knee feature built into the circuit. This means that the ratio will start low and will then increase in direct proportion to the amount that the signal exceeds the    threshold. Everything from mild to fairly heavy compression settings are possible. The compressor is a very flexible circuit that has both smooth and natural sounds. You will be able to control the dynamic range of your instrument while simultaneously preserve it’s tonal character.

Output – This knob controls the level of the output signal from the compressor to the next effect in your   signal chain.

CLASSIC AMP

The Classic Amp was designed to simulate the classic tube amps that Joe has used over the years. The sound of these vintage amps is legendary and can be heard on countless recordings that Joe has made through out his career. The controls on a classic tube amp were designed to be simple and straight-forward and the same is true for the Classic Amp.

Bass – This control allows you to cut or boost the low frequencies of your guitar or bass. The EQ curve is very smooth and versatile. You will be able to dial in the right amount of low end to give your guitar punch and power while still retaining low end clarity.

Treble – The treble knob allows you to adjust the mid and high range frequency spectrum of the guitar. You can dial in the right amount of mids and highs without making your guitar or bass sound to brittle or harsh.

Gain –  The gain control is very versatile. At lower settings (counter-clockwise) there is very little or no gain at all introduced to the signal. At this setting your bass will sound warm and full with no distortion. Keeping the gain control in this position will really allow you to experiment with the EQ settings. You can make some fine adjustments to your sound by simply experimenting with the bass and treble controls. Turning the gain control up (clockwise) introduces distortion. The distortion that the Classic Amp produces is not over the top – like that of a fuzz box. The sound breaks up naturally while at the same time retaining much of it’s clarity. Turning the gain up (clockwise) will also give your bass more drive and attitude. Experimentation is the key to unlocking the potential of the Classic Amp and the JWDC in general, so we encourage you to experiment with the pedal often.

Output – This knob controls the level of the output signal from the Classic Amp to the next effect in your signal chain.

PRE/POST SWITCH

The Pre/Post switch allows you to place the compressor before or after the Classic Amp in the signal chain. With the switch in the “Pre” position (down), the compressor is placed before the Classic Amp. With the switch in the “Post” (up) position the compressor is placed after the Classic Amp in the signal chain.
