I never really saw a use for a compressor, for me. I want it to be louder when I dig in or hit the strings hard. That's kinda the point.
Clean overdrive? Explain. I like not having any compression because it means when I dig in, it distorts the amp a bit more.
I think you're not really familiar with compression.
You may be right about distorting when digging in. I also dig in from time to time, but I don't like distorting.
Different strokes for different folks.
Maybe that's why I'm so fond of compression, because I love a clean sound.
But don't think that a compressor will kill your dynamics per sé.
You can set a compressor to do that, but mine is set so it doesn't kill my dynamics.
I have total tonal control, from sharp attack to thumpy.
I would say I use "light compression",... but that term doesn't mean anything if you don't know what exactly is going on.
My compression ratio is about 1:5, which isn't exactly considered "light" or "a gentle touch".
If I turn ratio up more, then the sound gets squeezed.
This is off course with my bass and my playing technique. YMMV
I use a rackmount compressor with more tweaking options. I have the threshold fairly low.
It's needed for my purpose IME for my passive precision bass.
Especially for the G-string with it's dead spot.
Plus I have bright piano sounding strings, somehow my tube compressor reduces the harshness of the D and G string. (I don't know exactly why it works like this, but hurray for my purposes.)
With an equalizer after it I can tailor my sound even more.
And it still all sounds natural.
I fooled around with my compressor toward settings that get my sound all squeezed and killing the dynamics.
Got some cool sounds out of it.
Set it to hard knee compression and fastest attack (something you should do with a bass guitar signal) and I got a strange envellope to my sound.
Almost like an artificial clean synthesizer bass sound, with a little bit of volume swell, fatness swell after the attack.
You have to decide for yourself if you need the features of a rack compressor... or a simple controlled pedal compressor.
But study up on how it's supposed to work, and if you test one out try to pay as much attention to the sound. How the attack alters and how you get sustain.
