Amulet of Hidden Strength and speed weapon

[Michael Grate]

I'm looking to get both for a DPS based archer (I'm trying to give him more hits per round to stack with manyshot and rapid shot). However,

This glass teardrop hangs on a platinum chain and can be used once per day to grant a surge of power. This surge can be used in one of two ways. As a swift action, the wearer of the amulet can make one melee or ranged attack at his highest attack bonus.

So would these stack then?

They seem like the same thing but they read somewhat different.

You could use both in the same round. Speed doesn't use up your swift action.

I think the issue here is not the actions used but whether the extra full-BAB attack granted by the amulet is considered a "similar effect" to the extra full-BAB attack granted by Speed.

Fortunately, this FAQ for the ki pool also applies to the amulet:

Monk: Does the extra attack from spending ki as part of a flurry of blows stack with the extra attack from haste?

Yes. The extra attack described in the ki pool ability doesn't say it works like haste, nor does it say that it doesn't stack with haste, so the monk would get two additional attacks (one from spending a ki point as part of a flurry, one from haste).
