This microphone has a very linear response for low and mid frequencies, both on- and off-axis, and then it drops off rather steeply above 5 kHz, but in a smooth and controlled way, with no ugly resonances.
This very mellow "old school ribbon" character makes it sound really sweet for drum overheads, and it really brings out the soul with trumpets and saxes. It can be quite useful for miking amps too, depending on what kind of sound you're after.
But it would be a pretty poor choice for acoustic guitars, and it would make the dullest vocal microphone ever! For such sound sources, where you need a more extended frequency response, I'd recommend a slightly more expensive ribbon, like the Golden Age Project R1 MK2.
Or of course a Royer, if you can fit it into your budget...
This one is tremendous value though, no doubts about it! Not only is the microphone itself really sweet, but the accessories are better than you have any right to expect at this price point.
In fact, there are microphones sold for 10x the price that come with no accessories at all. But here you get a well designed suspension mount, and a wooden box for the microphone, PLUS an aluminum box to put the suspension mount and the wooden box in!
Kind of over the top really. "I heard you like boxes, so here's a box for your box so you can have a box when you open your box!" What were they thinking?! Overkill much...
Anyway, short ribbons (1") are THE choice for drum overheads IMO, and a pair of these are basically as good as any others for the purpose (yes, really!). There are other cheap ribbons, and some of them have more extended treble response, but none of them sound as uncolored in the lows and mids as these, if you ask me.
If you feel they're too dull you can always just boost the treble a bit, these microphones handle EQ well, but I personally don't think this is needed (or even desired!) for brass and drum overheads. This depends on how aggressive sound you are after, of course.
