Excuse my ignorance but... :roll:
How does a push/push differ from a push/pull, it def. sounds like a better idea.
Push/Push - you push it once to engage, push again to disengage.. on my Ibanez, you can't tell if it's on or off without listening, but some designs sit differently (ie it may be higher when engaged)
Pull/push - Pull up to engage (will sit proud a bit) push back down to disengage.
I'm used to both, I have push/pulls on my Smithys and push/push on my Ibanez.
Most people seem to find push push easier though.
I like pull push, as often I like to roll down my volume at the same time as splitting the neck bucker, and that's easier to do in one movement with a pull push.. sorta a grab and twist kinda thing lol
