Yeah, a little difficult to see without comparing two pics side by side, but the coils on these are fatter than a regular roundwound string, so there was some getting used to them. If I remember correctly, they tore up my fingers pretty well the first couple times I gigged with them. I will add that this will be the first time I've used these on a 5-string, so I imagine there will be another learning curve because of those fat coils on the low-B.
