I didn't use a compressor at all, for well over 40 years. I dabbled with a few, both in pedal form and on amps like my old Trace Elliot AH350SMX. Even with dual band compression such as on the Trace I could never find a setting that I liked or one that really did anything for my sound. My view on compressors is that, unless you are using them for a specific effect (and I'm not big on effects) they should be applied very lightly and be transparent - and if they're transparent to the point that you can't tell that they're working what's the point?
So, I've been quite happy using my fingers to control dynamics. Until a few months ago.
I bought an ART ProChannel, mostly for it's EQ so that I could tweak my sounds for the room and also because it has a thumping great output that has no trouble in driving the rather insensitive Crown 1000XLS that I use as my power amp, but the ART has a compressor (in fact it has a choice between tube and optical compression), so I thought I might as well try it since it was there.
After a bit of experimentation I've found that I prefer the optical compressor and I set it relatively lightly (otherwise it does sound squashed) but get the settings right and it lends an indefinable quality to the sound that I really like. It still allows you to play softly or really dig in and control your dynamics just as you would expect, but it seems to add a certain polish and sparkle to the sound - it's hard to describe a sound quality in words but the best I can think of is that it's still me, but better. It really is very musical.
Anyway, I'm converted after all this time. Maybe it's finding a compressor that you like rather than judging all compressors equally?
Oh, and to all those people that think it's a crutch for poor technique, do you really think there have been any albums recorded in the last 40 years (even live albums) where the bass track wasn't compressed to some extent?
