Behringer CL9 Compressor Limiter

I'm very surprised with this pedal. It's very good for what it costs.

I bought it to built a small pedalboard, light enough to be taken on public transport, which I would use on rehearsals (I don't like to carry my main, large pedalboard).

This compressor is better than I expected; first of all it's transparent and quiet. Well, I can hear some hiss, especially when I increase Sustain, but it's because it amplifies all quieter sounds including hiss coming from single coils.
It doesn't color a sound like dyna type compressors (with might be your thing or not), but it's different type of compressor. This is limiter type, so it works best for me as a last pedal in the chain. Not that you can't put it first. The is no right or wrong here - the best is what works best for you.

Pros: transparent (doesn't color a tone), quiet
Cons: plastic enclosure

The Behringer CL9 is an amazing compressor. I bought mine to use with my 12-string guitar, and for that application I found that it brought out jangle exactly how I wanted it to. With my six string guitars, it gives me a chewy compressed character that I enjoy.

The pedal's plastic enclosure, of course, leaves something to be desired. There also aren't many parameters to adjust. I don't view this as a positive or negative; the ease-of-use means you won't spend much time adjusting the controls here. It's convenient if unexciting.

There really isn't much else to say. Like with all of the plastic Behringer pedals, the circuit is great, but if you want something more durable and long-lasting it might be worth spending the extra money for something else.
