Title: Z Bar Alternative
Post by: Thomas Bishop on January 21, 2008, 09:43:48 pm
I work with a band whose guitarist plays through a 4x12 cabinet "permanently" mounted in a road case.  When the lid goes on it is only a couple of inches from the grill cloth.  I want to be able to mount a mic so that it can stay attached when the lid is on, but the typical Z bar is not an option since it would stick out too much.  Drilling into the case is not out of the question, so any suggestions you might have would be much appreciated.

Is it a sealed cabinet, or could you mic it from the back?

Unfortunately, it is a closed back cab.

Can you mount it inside the cabinet? Experiment with different locations behind the speaker.

I like that idea but I'm afraid he won't go for drilling holes in the cabinet to pass a cable through.  I'll run that past the board, but I think any carpentry work will need to be done to the case rather than the speaker cabinet.

I am sure you could come up with a way to secure an e609. What about those amp clamps ?  ampclamps.com You could probably gaff tape a 609.

Atlas has a wide variety of flanges and other permanent-install hardware for microphones, if you don't mind drilling into the case.

Or just get a Z-bar and cut off the section that sticks out behind the mic.  If that won't fit, your mic won't fit anyway.

Another approach might be to use a microphone like a 609 or a 906, and an appropriately-colored ratchet strap to hold it against the amp during transit.

What about a drum claw? That might be the ticket...

That Amp Clamp looks pretty cool.  It may stick out a little too far, but I'll definitely keep that in mind.  I am using a 609, so I've got the low profile covered there.  I'll take a look at the Atlas products too.  A drum claw would be okay (the Shure A56D is really cool) but wouldn't stay attached bouncing around across the country in a trailer.

If you removed the grille, you could attach the 609 on a metal strip screwed across the cone, then put the grille back over it. Invisible, except where the cord comes out, but if you want to get even more stealth, the cord could be routed through the back of the cabinet and be wired to a panel mount male XLR.

Here is a very unorthodox suggestion, but I did use it once to good effect.

Take a Crown PZM 30d and tape it over the cone you want to mic.  Give it a stable phantom supply, and set the eq on the mic to "flat" and prepare to be surprised.

Its not right for guitars in every genre, but it will take the SPL, and it was great for lead tones on a fender twin where I tried it.  The PZM 30d does not have any proximity effect like a typical cardiod mic, so don't be surprised if it needs a little low end eq boost (try a low shelf starting about about 300hz).

PS, my situation was a stage volume situation.  We ended up placing the amp up against a road case, and then stuffed a blanket in a case lid, and sandwiched the mic between the amp grill and the lid/blanket combination.

Hope that helps!

Depending on the cabinet the drum claw might not open up enough.  I did find an LP thing with a butterfly clamp that will hold on to the lip of my Bogner 1-12 (which has a similar thick lip to the Marshall and other 4-12 cabs).

It sticks out past the cab about 2.5" and has an offset rod and swivel that puts my 609 wherever I want it.

Good man, Phill.

I will stick any microphone on any instrument just to see what happens.  The uses for the Crown PZMs seem to be never-ending.

They do pretty well at the base of a digeridoo.... :-)

That is an almost impossible "instrument" to reproduce.  I remember some guy bringing one into Blake's in Berkley one night.  They stuck a 58 on the floor in front of it and it boomed like crazy.  One note wonder.  Oh wait, the thing only makes one note anyway.  But the proximity of the end of the thing and the floor made a real mess.  A PZM actually makes sense.

What about just making a small metal flange and using the hardware from the Z-Bar? Or as Rob Timmerman suggested, just cut off the tail of the Z-Bar.
