The band I play with have been recording some tracks to put a CD together to assist getting gigs.
One of the things that has bugged me was the fact that the sound man wants to re amp my harmonica in a post recorded session. He's been putting a DI box between my mic and the amp input.
We're doing this in a garage so a no frills situation. He wanted to minimise the spill as much as he could.
But I've invested quite a bit and my gear and now the Princeton is back and fixed and I've installed the Li'l Buddy I want my sound recorded not some after process that's not what I've played myself.
I did a google search and found this company Integral in the UK that does a 10" and 12" internal mic that fits between the speaker baffle plate and speaker. Here's a link Integral Close Micing thought this may be of interest. I like it because it gives me a line out that won't affect my warranty as it's so easily fitted or removed. I think Will Wilde uses one?

I'm don't have much experience on this, but here's what I think:
The way he places the DI box won't capture your amplified sound;
the Integral Close Micing is a interesting device but won't prevent from spill, since it's like a close miking
The best solution would be: 1) put your amp on another room or inside a box to prevent the spill
2) put the di box between the amp and speaker jack (paralell speaker jack)
3) create a impulse response of your amp and then reamp your harmoica. This way you will loose almost nothing from your tone.

A lot of this makes no sense to me -- but I have very limited studio experience. Why there would be a DI box between your harmonica mike and the amp input is beyond me. If he wants to "re-amp," hasn't the spill already happened?

The ICM could be handy I suppose, but "close micing" has never seemed that complicated AND unlike the ICM, close miking allows you to position the mike other than right at the speaker cone (harshest location).
I may well be missing something here.

You are connecting you mic straight into the DI BOX? most DI box have very low input impedance and that can affect your tone. It is better to use an active A/B/Y box to split the signal.

If you want the sound of your rig, why don't you reamp through the Princeton then? it would be almost the same.
Sorry for any misspell, english is not my first language.

This product is interesting, but...I was always told not to mic in the center of the speaker, but to one side. I noticed the stage hands always do that too.

That looks pretty interesting, but there's really only one way to answer any and all questions. Buy one.

Looking at the Integral site, it says the mic is actually pointed away from the center of the speaker cone, even if it is located there. Maybe that helps?

Did this sound guy make the guitar player go straight into the board? I can almost guarantee that's a hell no. I think at the very least, you should get a line out for your Princeton. You'd get the tone of those tubes, but not your speaker. Way better than some shitty distortion by a computer program which is what you'll probably end up getting. That speaker clip-on contraption sounds great, but if you're handy they're bone simple to make and install for a few bucks.

Yep, I bought one. So I'll give some feedback once it's fitted though I probably won't see it this side of Christmas.
Hi Markdc70, that's exactly what I was thinking! Anyway, it's on the way now. I just hope I get some work that warrants the effort of ordering it!
