Making "fancy" Dynamic Microphones...D700 Bi-directional Update!

[pinchemotherloaf]

Just for fun, 'cause that's what this is about, I made a couple of more dynamics in "fancy" mic cases. This is just an experiment and the results were fairly good. The TLM clone body with the SM57 cloned motor has a Shure 51A3030 step up transformer in the base. The black mic has a KAM RT1 motor with a Shure transformer. I tried to make out the grounding the best I could and used the 'gold plated' connectors provided. Found everything on ebay. Cost for the TLM clone body $40, black body was $20, Shure transformer $12, SM57 clone motor $8, KAM RT1 motor $20

Interesting projects! I once did something similar, not quite as fancy but almost daily in use.

An old Schuman MDS3 with new dynamic cartridge, I tried a few. Among them also replacement cartridges for SM57/58 from China.

Now I have a Beyerdynamic capsule in it from an obsolete wireless microphone.

what do they sound like compared to say a 57 or 58?

Sound is similar but different. The KTM capsule is flatter sounding , not much mid range bump like the Shure. The transformer is not recommended for the KTM but I used it anyways. Nice, fat, dynamic punch with plenty of output, very little noise as well.

Looks like the clone 57 I'm using from China, They sound quite good for $8. Have you tried inserting a transformer as well?

Yes, I had tried a simple China Clone transformer briefly, but I found it not so good. The sound of the China catridges on the other hand is quite good (for the money), I found them somewhat harsh in the treble compared to a real SM57 and perhaps a bit thinner. But the differences are small and actually only audible in direct comparison.

47 Update: Added a very fancy SM58 inside a clone U47 body! Why not? It sounds actually quite good. Not as good as a real U47, but maybe as good as a SM58. I added a piece of felt to dampen the headshell. Loud and very quiet too. Good for stage use.

does that have a cutout for pattern switch?

No, just the hole on this body. They include a..sticker to place underneath!

does the headbasket have a hole?

does the headbasket have a hole?

Yes, just the headbasket, not the body portion.

Update: I took this cheap mic body, and mounted a KTM shure clone motor with the rear vent opened up (removed the cap to make it fit!) and a shure transformer in the base. The result is a bi-directional dynamic that sounds a bit funky but usable, maybe! Because of the body style, I've name it the D700 Case $20, KTM Motor $17, Transformer $12, Fun $Priceless

Applause for the red stuff

It was included in the body kit! I figured it could dampen the headshell.

What would be a really good option for dampening headbasket resonance? Is foam the way to go or is something like a felt disc better?

I was told once that thick felt is best. It's sold at sewing shops.

I've got to ask: Where did you get that case? I want one.

Edit: I found something similar, but not at that price (especially after shipping!)
