Hello and welcome to The House of Chrome.

 You are looking at a very nice older Shure Brothers 540 model dynamic microphone from the 1960's. It's a Sonodyne II model that was sold as a "general purpose" microphone that is an all metal design with satin chrome finish and has a more aggressive look to it. 

 I usually sell all my mics with cables to make operation easy but I also understand that sometimes a potential client already has a good cable and just needs the mic so here's a chance to get a perfect working 540 mic minus a cable that is ready to go. 3 pin cables for these usually run around $50.00 or more. If you have the vintage screw on 3 pin type (same used on the Shure 55, 55S, 55SW & PE54) then this will be a better deal for you in the long term. If you do need a working 540 with a cable included I do have one listed currently and ready to go. 

 Pic # 2 is from an old Shure Brothers catalog I have showing all of the mics performance characteristics. This was a more affordable dynamic mic compared to the more sophisticated and far better sounding dynamic cardioid models of that era such as the Shure 55S and Electro Voice RE10. If you needed something reliable for general broadcasting, paging, etc...this was your go to mic. These happen to make excellent harp mics as well with a gritty tone being void of bass and excellent overdrive. 

 The 540 does have an adjustable bass screw in the rear of the head as seen in pic# 9 which does work and gives you a bot of control over the tone.

 The 540 series mic is omni-directional so it tends to pick up more surround sound. 

 As you can see in the pics provided the satin chrome finish has a beautiful luster and shows extremely lite wear after all these years. There are no engravings, scratches, nicks or fractures anywhere on this 540S. There is just a few tiny blemishes. The black plastic looks pretty nice too with a couple small scuff marks. Just some extremely lite wear on the Shure badge. The front grill is free of any dents or tarnish and a new inner foam pop filter was installed to help with sound characteristics. This mic is a real gem.

 The joint mechanism holds firm as it should and the head pivots back and forth as needed. The Shure front and rear labels look incredible. I'd rate it a very conservative 8 + on a scale of 1 - 10.

 This mic will screw onto any microphone desk or floor stand you might be using.

 Again, the mic just needs a 3 pin type mic cable to operate.

 MICROPHONE STAND IS NOT PART OF THIS SALE...FOR DISPLAY PURPOSES ONLY.

                     As with all my vintage microphones...
