I recently picked up a very slightly used Mapex Armory Dillinger. I bought new heads (Amb snare side and Remo CS on top. While replacing the heads and tuning up, I noticed how much stiffer some tension rods were than others. I was tuning up with a key on each side and going in a star pattern. All pitches were correct but I'd have some tension rods that felt very tight and some that turned smooth and "felt" looser, though the head was tuned. Is that just the drawback of less expensive snare drums? I was actually thinking about getting a 12-24 tap (I think that is the size) and retapping the lugs. Anyone else run into anything like this? I did put a bit of lithium grease in each lug to coat the threads. That didn't have much effect on the non-smooth feeling of many of the rods. Maybe I should buy some new lug inserts? I hate investing much in this snare. It looks nice but it's kind of obvious the hardware isn't great.
