I am doing a song and want to record my bass amp. I have a carvin stack with a 15 and 2-10 inch speakers. I tried to just run the bass direct into my isa 428 with a rnc off of the side chain. I did not like the way it sounded. No punch. I am going to try a D112 on the 15" and sm57 on the 10"s. I don't have a DI box so I want to capture the sound of my rig. Has anyone out there done much bass amp miking?
