From the seller

Hello and welcome to The House of Chrome. You are looking at a classic Shure model microphone known as the 545SD model that was sold sometime during the 1970's or mid 1980's and was the industry standard having excellent tone and used for a variety of purposes. It comes with the original Shure A-25 model mic clip, short cable and original mic pouch shown in which to store. This is a Hi Z version of the 545SD. More on that in a moment. The 545SD originally came out in the 1970's and was initially an American made model but it was eventually made in Mexico around the mid to late 1980's. The mic is still built today but I believe it's been made in China for the past 25 years and is called the 545SD-LC. This is the 1st generation American made example and it's a real gem. This 545SD has been thoroughly gone over and cleaned. It's quite nice and works like new. The 545SD is an absolute work horse and they tend to hold up very well despite being decades old. Pic # 2 shows this very mic in a 1980's Shure catalog showing the 545SD as well as a few other 545 variants being manufactured and sold along with their characteristics. The 545 series mic was a very rugged and reliable model mic that holds up well with time and use. If you are looking for a mic with excellent tone and frequency response for singing and broadcasting then this example will certainly foot the bill. Excellent uni-directional characteristics as well. Probably the most popular and certainly one of the most rugged mics ever developed in the past 40 years. The 545SD was sold in the low Z version mostly but Shure also sold this in Hi Z and the Hi Z versions came with a special cable as the Hi Z 545SD was wired differently inside to get the Hi Z setting. You needed that special cable to operate the mic as the cable was also wired specifically for the mic. On a Low Z 545SD the positive wire is # 2 but that is not the case for the Hi Z version. Anyways, the mic is provided with the short 7 inch cable shown that is properly wired. Simply leave the short cable attached to the mic at all times and attach any longer standard XLR cable of choice to your audio equipment. You'll have no issues so long as this short cable is used with the mic. I built the cable myself so it will last for decades to come. There were two quality Switchcraft connectors used as well that are in excellent physical condition. As you can see the mic itself is in very nice overall physical condition. The satin chrome absolutely glows. No scratches, pitting or scuff marks. The black plastic cartridge shows just a couple tiny scuff marks but it's free of fractures or scratches. The Shure label shows no wear and completely legible. The front screen is free of dents or odors but there is lite tarnish. The original foam inner pop filter was replaced as it was completely gone from older age. If you buy an older 545, 545S, 545SD or 545L model mic it's crucial that the old foam pop filters are replaced to get the best sound performance from this mic. The 545SD comes with the on / off switch and the switch works perfectly. No issues. The cosmetic condition of this mic is an easy 9 + on a scale of 1 - 10. The original Shure A-25 mic clip works perfectly giving you a firm grip on the mic with a wide range of tilt. The clip looks very good with lite wear and the tension in the joint mechanism is adjustable via side screws. The mic will screw onto any desk or floor stand you have. The newer Shure mic pouch is vinyl and comes with an excellent working zipper. It's a great place to store the mic when not in use. It's in very nice condition as well with zero exterior wear and works excellent. I sold all of my other American made 545SD mics in Hi Z the past year and this is only one I have to offer currently. This mic is ready to go! MICROPHONE STAND SHOWN IS NOT PART OF THIS SALE AND USED FOR DISPLAY PURPOSES ONLY... As with all my vintage microphones and stands...
