Subject:Re: two mics on top...

Hi Mark,

I use SM57's in stereo -- two for the top, one for the bottom -- which greatly improves the Leslie image, IMHO. Like you, I was not able to mount the second horn mic inside the case, but I did come up with a solution:

- Mount a "tee nut" or other threaded stud inside the upper opening, about 1" from the edge, roughly in line with the shortest point between the horn opening and the edge of the Leslie. I used an old threaded stud from a Rhodes Stage Piano, but that's just because I happened to have one in my parts drawer. In the case of the tee nut, it should be mounted from the underside, and glued or strapped in place.

- Make a short adapter to attach a mic clip to a flat bracket, and then attach the flat bracket to the tee nut with a knob-bolt -- like the one that holds the legs to the Fender Rhodes, of course! You can buy those bolts at hardware stores. If they only have the threaded nut style, buy a bolt of the same size, cut off the head, and epoxy the threaded rod into the knob-nut.

- If you can find them, there is a guitar mic adapter called a "Z Stand" that works perfectly for the mic adapter. It's meant to adapt a standard mic clip to a combo amp by hanging through the carrying handle, or a speaker cab by mounting under the cabinet. The part that goes under/over the amp is about 8-10" long; cut it down to about 3" and drill a hole for the knob-bolt.

The third mic takes about an extra 15 sec to set up, and the adapter can be left behind for mono gigs. If there's enough interest, I'll post a picture.

Regards,

-BW
