4 knobs:

Tone, Level, Attack, Sustain

Cs-3 as the original what.
Only the LED has changed and stickers msm workshop t have additions.

UTILIZATION

The use of the pedals is the same and I have not even changed my rglages (which sounds ten times better now.
I also want to prciser as mine was being directly modified in the workshop and it really work fast srieux and trs.
In addition, the MSM guys are really nice.

SOUND QUALITY

The effect remains on the cs-3 compression of the original but sublime as no more breath in clean background even with the sustain, trs little saturation compression and more transparent and warm as before.
It really takes all its meaning on an amp lamp APRS me.

OVERALL OPINION

I come from rcuprer and I am very pleased.
I look forward to the next rintgrer my pedalboard rpt because now it's a really really great pedals with the quality.
Do not hesitate to change your. (I even bought me my cs-3 OCCAZ for once)
Compression of this quality the price is really the deal.
