I've been using a cheap used drum kit for the past 8 months or so. It doesn't get the greatest sound, but it gets me by and it's good for practice.
The only complaint I really have is that the hi-hat makes a horrible clanging sound (even when closed), instead of the nice
tss sound that you expect from a closed hi-hat.
Now perhaps the real answer to this question is buy a better hi-hat, but falling short of that are there any tweaks I can make/techniques I can follow to get a better sound out of the hi-hat?
