Squish Squash your chicken pickin' ~ Ibanez CP10 Compressor Sustainer



This was my compressor for over 4 years. Its a subtle effect, noiseless and tone stays true. I place it after my main overdrive and then before all the preamp, modulations and delay. It sounds more professional when I place it that way instead of the beginning of the signal chain as suggested by most players. Its a fine compressor but mainly I use it to squeeze out the lower harmonics to drive' em much higher. All mildly played notes gets compressed higher so you'll hear it much louder and notes with much higher gain in the lows or highs gets played within a spectrum range I set (not too high freq if there's too much bass and treble).  The picking dynamic stays intact with no squished notes. I bought it used and so far its flawlessly working. This one is hard to come by these days. Its now discontinued by Ibanez in the early 80's and this one is possibly an '82 during the 10-series models based on a Tube Screamer Model # reference that if it starts w/ a "2" then 1982. Made in Japan. Very similar effect to the now vintage and fabled MAXON CP-9. As always, the one pictured above is the actual pedal I have. I still haven't decided to sell this one but if anyone's interested just message me up :)



CONTROLS:

ATTACK:
The attack control is also set all of the way off for the fastest attack time. Turn this control up for longer/slower attack times. This is helpful for humbuckers or bass guitarists that want a very punchy tone.

SUSTAIN:
You can use this control to give a sustain effect with almost no increase in noise or high frequency loss.

LEVEL: 
Use this control to match the bypass mode signal with the effected signal. You can also use this as a volume boost during solos. It provides the ability to overdrive your amp if you choose. To use the compressor as a lead boost, simply turn the sustain all of the way down, and then use the level control to drive your amp into a sweet overdrive tone.

    Features

    Compressor/Sustainers, unlike distortion effects, do not drastically alter the sound (distort it) to create sustain. Instead they maintain the basic integrety of the original sound while at the same time adding subtle changes to the attack and sustain. They also even-out the overal output gain, providing a clean, uniform sound. The Ibanez CP10 Compressor/Sustainer is a high tech, studio quality effect in a compact case. It's ultra low input noise (-107dBv) combined with the latest VCA circuit provides clean, distortion free compression and sustain. The CP10 also features three controls giving you complete control of the attack time, sustain and output level.

    Principle

    The CP10 Compressor/Sustainer is an effect that controls the envelope of sound, which is actually time's effect on volume. The three controls on the CP10 allow you to contour the attack and sustain to taste. The Attack knob controls the level of the initial attack. The Sustain knob controls the threshold level, so that if the volume is too great, it is compressed and if the volume is too slight, it is boosted, keeping a constant output level.

    Use

    Compressor limiters are used very often on vocals or extremely dynamic instruments to give uniform volume or amplitude in many applications. Peak levels are limited so tape saturation won't occur in a recording situation, allowing higher recording levels which increase signal to noise ratio. Dead spots on certain instruments can be eliminated live and in the studio. Stage monitors can be heard better when soft vocals normally would be buried, yet feedback can simultaneously be controlled by keeping a limit on the volume, helping to prevent the need for unnatural over-equalization. These applications aren't typical of how a guitarist uses a compressor but keeping them in mind will lead to efficient and creative use of the CP10. Most often a compressor is used on a guitar to influence either the attack or sustain portions of the sound. To emphasize the attack, gradually increase the attack control. Too much emphasis can ruin the sound by eliminating the sustaining pitched portion of the sound. Be sure the sustain time control is set at a moderate level when emphasizing attack to eliminate this side effect. This usage is especially nice for muted or "blocking" styles of playing. If the sustain is set too high, notes following a heavily attacked note may not come out well because the CP10 is still sustaining the previous note. Another major usage of compressors is to add sustain without distortion. Sustain isn't actually added but as the sound naturally decays, the CP10 increases it's gain giving the impression that the sound isn't dying out but sustaining smoothly. Once the signal has dropped below a certain point, the compressor can do no more than raise the level of the remaining noise. Careful adjustment of the sustain control to playing techniques can keep noise from getting out of hand. Low sustain levels are useful for limiting applications.
