i think imma upgrade to Delta 44 for the soundcound ... any suggestions ?

and im clueless on the mixer i should use...suggestions ?

and anything else i might need ?

if the mic is a condenser then u have to get a digital mixer wit phantom power. Berhinger is the good shit, also rolands, tascam, anyhting digital thats cheap
