"I happen to have an original 1955 Stratocaster! The neck and body have been replaced with top quality Warmoth parts, I upgraded the hardware and put in custom, hand wound pickups. It's fabulous. There's nothing like that vintage tone or owning an original." - Chuck H -
This amp came to me with Omron relays that have the coil marked with a polarity. Further, after pulling them out, I verified that when connected per the markings, the relay fired...and when reversed, it did not.Comment

Some relays with low power coils have permanent magnet assistance, hence the coil emf has to add (rather than subtract) to this, so is polarity sensitive - I've used omron relays with this spec. PeterMy band:- http://www.youtube.com/user/RedwingBandComment

Some relays come with a built in diode and this is a reason to say they have polarity otherwise Enzo is right. I'm using those instead of Vactrols all the time. They have two versions - without and with built in diode /product # ending with D/.
