Not just "compress the sound", because I don't know what that means exactly. If I were to put a compressor into my setup, what would change in the sound?
many use it to hold notes longer... or use it as a gain booster. at high settings it boosts the attack of notes you play. it also gives off a lot of feedback when on.
Compress the Sound ;-l
evens out the low mids and highs. when at max itll sound like californication where you wouldnt be able to tell when your striking the strings hard or soft.
