First of all I am massive fan of dome knobs on my guitar purely for :
-easy installation
-even when sweaty easily turn
-Durability
Down sides:
-colour options
-not for everybody, predominantly limited sizes
-Can be a pain to adjust
That being said, these Ibanez sure grips pretty much cover the best of a lot of of potentio knobs. The grip is there, the looks are there, easy installation, great look to it and overall a steady little piece of gear.
