Honestly, when I first tried out GNB at the start of ShB I was turned off by the weapon sounds. They sounded really weird and... "tinny"? It didn't have a proper slash sound and was really off-putting. The current sound effects aren't perfect, but that's probably because they didn't have the time to go out and record new sounds, so they just edited the sounds they had which is how we ended up with the bat-like "woosh". The main culprit is the "woosh", which was probably pitch-shifted a bit too far down and now gives the wrong impression.

The higher-pitched tinks and shinks are still in the sound and I like those as they are now. The "woosh" just needs to be shifted or replaced or lowered in volume so it's not at the forefront of the sound effect. Even in edits I've seen on YouTube trying to show the sounds blended, the "woosh" still feels off, both in the old and current versions. The "woosh" has no weight in the old version (making the whole sound too tinny), while it's too heavy in the current version (making it sound like a metal bat).
