That is a good plan. This is a great topic for bassists playing in live ensembles. The "fixes" aren't always obvious, as evidenced by a lot of the replies. General speaking bass guitar is not limited to low frequencies and the conflict between the two instruments can have nothing to do a HPF or any EQ fix. If the two aren't playing things that mesh you can have problems... even playing an octave apart. Tower of Power's Chester Thompson and Rocco Prestia are a great example. Between them and Dave Garibaldi on drums, if one of them goes rogue the wheels fall off. But when they're "on" it's a phenomenal rhythm section. I learned that lesson early on. Knowing how to cut through in a mix, period is often overlooked. I've been gigging with a couple of basses strung with flats among other basses lately and if anything I find that they cut through even easier than my basses strung with rounds. Adequate amplification/monitoring is essential. You have to be able to clear yourself. If you don't have it you'll likely have problems with anyone who can drown you out.
