The Astatic 335H-7 mic - I love these things, have two of them, and they've become my main mic for gigging. They have a bright sound which I prefer (not muddy at all). And the small size and shape make them very easy to hold. The square profile fits your hands well. I cut the cable and put a Switchcraft female 1/4" plug on the end so they can be used with any guitar cable. I love these little mics!

My question for the vintage mic experts is about the different versions. Both of mine are 335H-7. But I've seen 335H and other numbers. I tried searching and can't find any info on the differences between the different models. Does anyone know about these mics or can point me toward some info on them?

Thanks,

It's been more than a decade since I owned any of that type, but If I'm not mistaking they made them with Dynamic and Crystal/Ceramic elements using different model numbers.

I had a few that came in some mic lots that I bought. IMO, the 7 designation doesn't exist, if it does exist, it probably came with a stand and is physically identical to the 335H
I do know the H is hi Z.

I have a 335H with very low response level. I suspect it may be a crystal and has gone bad. I got it for the look too! Art Deco baby. I'm not sure if or when I will ever be able to find an element to fit it for what I can afford but I'd love to have it out there at gigs.

@Harpaholic, Yes the 335H-7 does exist, I have two of them. You can get them with 335H or with 335H-7 stamped in the metal on them. Further research says that the 335H is high impedance dynamic, and the 335H-7 is high impedance ceramic. Some sound samples I heard on Youtube support this.

I just bought a 335H and when it arrives I'll sound test it against the 335H-7 to see how they're different.

I believe you Jim, but according to the 1975 Astatic catalog the 335 was only available as a dynamic.

There is one currently on eBay stamped 335H-46. There's a 335H-34 on an image search I did and a 335H-17 on Reverb.
It appears to be a manufacturer code??

@harpaholic

I thought about the -7 being a manufacturing code, but you find the -7s all the time. If it were a date code or similar the numbers would be more randomly distributed.

I have an old Astatic catalog and as you say, it shows the 335H as a dynamic. And no mention of a -7 version.

But, it really sounds like a ceramic or crystal. I bought a 335H and I'll sound check it against my 335H-7 when it gets here.
