I've had a couple. I think they have a high/low impedance adjustment. As for usefulness, it's somewhat similar to a SM57. Paul Butterfield and James Cotton are two notable guys who used the 545. I've had both the regular stick mic and the "pistol grip" type, with and without on/off switches.
The 545 can be a good harp mic or vocal mic. As with some other mics the gain and highs may need to be rolled off a bit. I liked using them in a stand to keep them "in the pocket" and try to cut feedback potential. I let them go at one point or another when I was minimizing my collection.
file:///C:/Users/Eric/Downloads/Model-545D_guide_en-US.pdf Always Google for info! 545 is a very High Quality mic in the Shure line. These will work well as a stage mic, into the board, or can be rewired to Hi Z for use into an amp. You can also use an in line, impedance matching transformer for use with an amp. Move the switch stop to the lower position so you can use the switch to kill feedback in an instant and to shut off mic when at rest. Very handy. I find that the 545 is very responsive to hand position going from clean to driven with cup alteration, more so then any of my bullets. The 545 is the predicesor to the Shuer 57/58 mics and has been in production since the early '60s. This is a testiment to the quality of this mic. You can drive nails with that SOB then take it to the gig. Feedback monster...not in my hands. The 545 may be the best mic I own. Just to qualify, mine is an early 545 Unidyne III so not quite the same as yours but yours is damn good also. My best advice is, take it out and play it. Make your own desision as to it's worth. Our opinion really means nothing but I like to give mine so, there you have it. Rock on...BN

Thank you jbone and Barley N. And of course I Googled! But I find that over here there´s a bunch of specialists who have experience from that particular *harmonica* aspect of electronics and whatever and I tend to shamelessly use that.
And of course I will try out my 545 in various ways, but there´s a bit of a problem for us living in apartments with no wish to be evicted: We got to keep a lid on our most energetic attempts at testing out new toys. And while at rehearsals, it can be tiring for the other guys when you´re absorbed by your own gear. By I gave it a sort of dry run just now: plugged in to a small amp just to see how high I could push volyme befor howling. While it was nowhere as high as my Audix and EV, it performed rather nicely.
So I will give it a shot already this coming Monday. Many thanks.
@1847: So by "output" you mean that the bullets mic(s) get louder before feedback? Surprises me. My impression is that with an Audix FB, say, you can get quite a bit more volume out of the amplifier, as well as the Electro Voice that I bought a while ago, which seems to me to be the most powerful of all my mics. But I have no measurments, only impressions.
Re-wireing is way beyond me, but the box, as you say, should do the trick, I suppose.
OK, thank you 1847. I just returned from a music store session of amplifier testing, and, interestingly, my EV PL35 outperformed the 545 SD on all areas: sound quality, loudness and even warmth. (But with extreme close cupping the 545 get rather cozy.) Interesting, because you can get five EV´s for one 545. This was mainly on two amps, I hasten to add, and I have no dog in any fight between mic brands. Just glad that I took the advice and purchased a EV.
I have one and I use it as my main recording mic for recording distorted harmonica. Sometimes I use it live, it sounds great, but it is a bit too old and wiring already failed twice so after last repair I prefer to keep it at home.
