Hi ! I'm a guitarist currently trying to grasp bass guitar. I've started learning finger picking, but I've noticed the difference in volume between notes (adding less or more pressure) I play which I can't always control. I'm trying to get the proper technique practicing at home, but I've thought about using a compressor to average the sounds during band rehearsals for the time being. My questions are: 1. Does a compressor change the tone of the guitar at all ? 2. Are there any major differences between cheap and more expensive compressors ? 3. Can I use a bass compressor with a guitar (or vice versa) without the risk of damaging the equipment like with an amp ? Thanks for you replies.
