| Talking steel strings here (haven't tried hex in Nickel), I found that the round core stings "bounce" more, emphasizing the reason we tend to dig in. The hex cores seem more controlled overall, but if you're digging to get more growl, then try the round cores.
Overall, pretty close, but you will notice a difference. I'm saying this based off using DR Low Riders 45-105 and Fat Beams 45-105, so I think that's a very fair comparison. |
