Hi Riker,

You do indeed have the newer amp version of the EP500. Alan mentioned this a few months ago that the EP500's that are now shipping do not have the trim setting anymore and that a subsonic filter was added... and of course you should have received an updated version of the EP500 owners manual to reflect this current feature set...

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
