Got these for a lefty yamaha, they are great metal knobs.
It fits the pots very well and they turn faster then the stock ones, they are not as wide as the stock knobs so its even better for a strat like guitar, gives more room for bracing or hand.
Good:
Its made out of quality metal
Good grip
Silvery look
Bad:
No alan key included.
I would recomend these over anything else like them.
