If you're noticing this while monitoring with headphones, the decrease in bass from the rear capsule is likely bass cancellation from being out of phase with the headphones.[/quote]
Thanks 22busy. You're right about this. I tried switching the phase at the mic pre and this changed the sound in the headphones as you would expect.
I thought that I'd mention (in case anyone else is building something like this) that the metal casing around the polar pattern switch in the mic needs to be grounded, otherwise the mic will pick up radio signals. For this mic I used a ground buss wire that runs from the xlr connector, through the center of the body, and then to the grill area where it is again attached to the chassis. All of the mic's electronics are grounded to the buss wire, as is the metal casing for the polar pattern switch. The mic is very quiet in terms of self noise.
Someone asked about the construction of the grill. I basically bent some wire mesh over the end of a rolling pin and used plumbers solder to weld it. You may read about that and see pics if you follow the link on the first post in this thread.
Thanks to everyone for all of the kind words above. :grin:
