Hi,
How much effort does the FOH engineer want to put into getting the "best" sound, or most accurate reproduction of "your" sound? If he's willing to dial it in, I say let'em.
Through all the clubs and all the summer concerts I've done over the years with all kinds of different sound companies and house sound guys, I've had a real mixed bag when it comes to getting my bass into the FOH. Most will just DI my bass. Some will take the direct out from the back of my GK800RB. Although I've been told it's noisy some sound guys either don't notice, don't care, or it's not really
that noisy or they use a gate. Only a few have both mic'd
and DI'd my bass. But never has anyone taken the amp's direct out
and mic'd the cab.
I have to trust the sound guy and 98% of them (IME) are very competent. I like efficiency so I'm OK with the soundguy plugging my bass into a DI box and calling it done. But I don't use any special effects pedals or anything. For those guys I guess you'd want to use the DI after your effects. But I do think it sounds best when my bass is DI'd to the house and the cab is mic'd. Then you can get more of my rig's sound but keep it tight in the house.
When I'm mixing my own sound from the stage I just use my cheap DI box. If
I'm doing sound on my crummy little PA you can bet the gig is small enough that I just want to spread the bass around the room a little while I have a decent stage volume.
All that to say "it depends".
Are you running your rig in bi-amp mode? I would think that if you are going to mic a cab then the speaker needs to be full range. When I used a 2x10/1x15 (full range) rig on stage the sound guy would mic the 15" speaker, place the mic about halfway in the middle of the cone but point it toward the voice coil. When mic'ing my 4x10 cabinet most sound guys would place and point the mic right at the middle of the cone, the halfway point between the voice coil and outer rim. I'm sure there are other configurations too, depending on what frequencies you want to work with. The voice coil has more of the highs and near the rim has more lows.
I think you should experiment and have fun with it, both live and recording. See what works for you.
Thank you for your indulgence,
