From the seller
Hello and welcome to The House of Chrome.
You are looking at a classic Shure model microphone known as the 545D model that was sold sometime during the 1970's to mid 1990's before being discontinued 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 and original mic pouch shown in which to store. The 545D was basically a 545SD without the on / off switch which some musicians prefer not to have on the mic. If you like the on / off switch then the 545SD is the way to go. The 545D 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 no longer being built today so these are very collectible and very high quality. This is the 2nd generation Mexican made example. The 545SD is still being built today but they have been made in China since about the year 2000.
This 545D has been thoroughly gone over and cleaned. It's quite nice and works like new. The 545D 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.
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. As you can see the mic itself is in superb overall physical condition. The satin chrome absolutely glows. The black plastic cartridge shows virtually no wear. The Shure label shows no wear and completely legible. The front screen is free of odors or tarnish but there is very subtle deformation. The original foam inner pop filter was not replaced as it's still in perfect condition. If you buy an older 545D, 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 cosmetic condition of this mic is an easy 9 +++ on a scale of 1 - 10.
Mic takes a standard XLR cable though none is provided. 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 nice and the tension in the joint mechanism is adjustable via side screws. The older 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 very lite exterior wear and works excellent. I sold all of my other 545D mics the past month and this is only one I have to offer currently. These are just harder to come by. This mic is ready to go!
