Bassist Compressor : Very good.. but

Overall, its a super pedal. Its doing its job almost perfect. No coloration, very transparent but you can feel that its there, you need to know a bit how the compression work so you can dial in according to the style that you are playing, there is a video of Mr. Keeley himself go check it.

One thing, It could be a little cheaper, maybe.

Second, sometimes im looking for the attack and release time settings. (There is a pro version for that which is more expensive obviously)

If the compressor is in front of the signal chain, and your tone is bright and present, you can hear the release happening rather slowly, and you can hear that down swoosh type of sound.

So, if im using a huge tone im using preamp first, comp second and using that as a high peak limiter, less compression.

Otherwise, for regular tones, comp first with slightly higher comp and lower threshold.

You can find your sweet spot in the end. Depending on your instrument and playing.
