I've been debating this subject for a while now and it doesn't seem to be getting better. I'm looking for a 4 10 + 1 15 full stack. I've played through the GK setup and it gives a great sound. It's also all that my bass instructor uses because he's endorsed by them. Although I've played through a Trace Elliot 4 10 and it gave me a great sound as well. I just can't really say which one fits better. I know GKs are very reliabe and that's what is leaning me towards it but i'm still not sure. Any help would be nice.
