This is a newb kind of question. I just received a used acrolite I bought on Reverb. I like it okay, but I'm finding that the throw off doesn't seem to have enough range, as in, I can't make it loose enough so that it fully disengages the wires and have it anywhere near normal tuning/tightness when engaged. Any idea what might be going on? It's hard to see how I could adjust the wires to change this, but I know next to nothing about setting up snares. Perhaps the throw-off itself is malfunctioning and won't open as far as it should? The handle is at maybe 45 degrees to the head surface when open, not even with it.
