I have: M-Audio Delta Hardware Recording Interface Tube MP project series mic preamp Sure SM57 Amp modeling processor 2 no name speakers and a receiver A computer & software Am I missing any pieces to the puzzle? Should I get a small soundboard? Better quality studio monitors? A condenser mic? An equalizer? A compressor? I'm trying to record guitar, bass and vocals in my room. My question is, what should I improve on other than obvious skill and practice?
