We are going to IEM's soon. My concern is what may sound good to the audience/mains may not sound good in the IEM's. For example, if I play my maple neck p-bass= too bright?, roundwound= string noise? Will it be too harsh sounding in the mix or not? I am running thru a Hartke VXL Attack pedal that adds some tube warmth to a Radial JDI D.I. to the board. I have warm sounding a 74' jazz & 65' P-bass both w/rosewood boards. When everyone plays, does it make any difference no matter what bass I use? I know using flats are a possibilty to solve all these concerns, but some songs sound better w/roundwounds. Please give feedback those who are readily experienced in this matter so I can get a headstart.
