I'm new to the game, and have a question about low end bass recording. My set up now, I have the bass amp mic'ed and running to my Yamaha AW1600 workstation. The hi end bass sounds great, the low end sounds muddy and basically drones on and on when i mix it down. EQ'ing has helped some. The sales guy at the local Guitar shop recommended using a DI box to get a better sound? Any recommendations? Is a DI box the way to go?
