What's the most common order for those that have a boost and a compressor? I would think boosting a compressed signal makes more sense because the output is more even to begin with. Any takers?
Compressors are usually among the first effects on the chain... is certainly more common to boost the compressed signal, but not mandatory!
I at least always put the compressor first.
I don't have a booster but I have my overdrive in front of my compressor. The comp changes the character of the od, makes it a bit tighter. The other way around doesn't do much for me.
