I bought a Soundcraftsmen G2241 EQ a few months ago and would like to know if there is any up-grades that I could have done to it. I don't have the knowledge do it so, I will need to have someone do it but first I would like to know if there is any up-grades that can be done. And how much the up-grades would help. I'm not to knowledgable to work on electronics I just like too listen to them. BTW is there anyone that has any info. on it?
