Hey guys I have a DM-9 clone and want to change the small screw on connector for a 5/8ths switchcraft, the threaded hole in the mic is too big! filling should be easier than drilling right? ok how would you suggest filling the the space to give a tight fit? the sound by the way is incredible!! I'd like to use this mic a.s.a.p.

Thanks in advance for any advice.

I can recommend to sell your microphone to BlowsMeAway Greg (http://blowsmeaway.com/) he is really master of microphone and connector things.

Unfortunately out of work at present, I have plenty of time and most of the relevent gear but with no job on the horizon cash is short so it is something I will have to do myself, all advice welcome. Thanks guys.

Without having it in my hands to look at it, here's a stab. I'd say you could probably do it with a couple of fender washers, one inside and one outside the mic body. If you can't find a washer with a large enough hole, you may need to drill them out yourself to get to the right diameter. Alternatively, hard rubber washers may be suitable replacements for metal, in this case, since you just need to hold the connector to the mic body. I don't know if the threads on the connector are long enough to pass through three layers, so this may prohibit you from doing this. Visit your local hardware store and see what bits you can find to make it work.

To add to what Seth said - Remember you will need a place to connect the ground wire, not just the hot one. Sometimes you can mount a switchcraft connector with enough of its threads showing to use the solder lug that comes with it - this is always the easiest. If not, you have to improvise. In the case of that mic, if it is what I'm envisioning in my head, what you need is a tiny bushing, thinner than the section thickness of the mic where it passes through - then you can use a regular lug and nut.

Seth, Greg, thanks so much for the advice. After drilling about 1mm into the original connection shaft I was able to pass enough of the Switchcraft through to atatch the lug and nut and my local plumber supply came up with a ridged rubber tubing which filled the gap left by the original connector, I now have one hell of a mic with great feedback resistance. I shall be using this one on Friday and Saturday night, the next two gigs I have. Thanks again guys, Tim.
