Forgive me if this is too basic, but I'm relatively new to the electric bass. I have a GK Backline 600 that powers a GK 410 cab. I'd like to get something more portable to take to rehearsal and smaller gigs. Should I get a 115 that I could also pair with the 410 for larger outdoor gigs? Should I stick with GK since the other is a GK? Or should I just get a small combo amp? I don't want to spend too much, but I want something that's going to sound great.
