Just curious what is your experience with really used old hi-hats that have grooves near the edges smoothed out as a result of a long use.
Do you feel like you get a weaker, less defined, quieter chik from them?
I have a 70s Paiste 2oo2 medium hi-hat pair and I feel like it might be the case, but maybe it's just how I position the - and they're not very heavy cymbals after all.
