I don't really understand compression, and you can't really go by demos, cuz compression is more of a thing you feel imo.
I've used two compressors, one was the Aguilar TLC which I hated cuz it had too many knobs which confused me, and when it was on it made my sound worse. The one I'm using at the moment is the behringer CS-9 which is based on the ibabez CP-9, but has better bass response. I like the way this sounds, and I don't have to think about what the knobs do too much cuz it sounds OK with them all pointing straight up, but it's cheap and not at all vibey.
So what I want is:
Something that sounds gentle, like it's just softly smoothing everything out and making everything sound subtly better.
Reasonably priced - around 100 quid used or new is fine.
Simpler the better. I don't want a lot of control, that gets me into trouble.
Preferably not a bass specific pedal, cuz I have an aversion to that.
