Boss CS-3 Compression Sustainer

A very simply designed and set up effect, and thus very easy to use. Level knob is essentially for your volume control. Tone this has an effect on your low/high end frequencies. When rolled up high you can hear more high end frequencies and it gives a clicking sound that feels like you can hear the contact with the string. Attack / Sustain - these two knobs I use in co-operation to achieve various sounds. With the sustain knob on a low setting the pedal acts as a limiter, while rolling it up high increases sustain and the length the effect lasts for. Meanwhile I adjust the attack value depending on whether I'm playing clean / overdriven. When at a low value the pedal produces a crisper and cleaner sound, while it allows more Drive when rolled up high.

Conclusion: Awesome compressor!

I have this pedal for the last few weeks. It is yet again another great product from boss with its rigid and functional design. I use this pedal for live acoustic performance's and im still getting to grips with its functions even after a couple of weeks. There is no doubt it is quite a useful tool but you just need to know how to use the pedal and I have and will spend a lot of time ajusting it to get it just right. I do find it very useful when I am playing guitar and finger picking, and then limiting when strumming hard. A good little pedal with lots of options available. Its a four star pedal for me.

I needed a compressor, so i decided to buy a not to expensive one.
The Boss CS-3 is built like a tank like all Boss pedals. It does its job. Nothing more, nothing less.
The controls are self self-explanatory.
Level - controls the level of the signal
Tone - controls the frequency of the signal
Attack - The more you turn this knob clockwise, the more attack you have in your sound.
Sustain - This one controls the amount of sustain. I don't know if it is technically possible to turn out the noise after turning the sustain clockwise. But there is a lot of noise if you turn on the sustain of the CS-3.
If you just want to have a compressor which adjust the level of your guitar/bass, you should give this one a try.
But i wouldn't recommend it if you are interested in the sustain feature because the noise is very annoying.
