If the URI in the data file does not match the URI in the manifest, then
it won't work, this is how the host discovers presets.  This URI is the
format saved by Ardour, it would not have come from anywhere else.
There is probably one in ~/.lv2/presets/

You seem to be suggesting that you saved a preset with Ardour, and it
has that "double hash" URI in the manifest, but the data file just has
<>?  I can't see how this could possibly be the case, nor can I
reproduce it.

For the time being I suggest you just not save presets with Ardour.  It
is broken, and will be fixed to do what Jalv does.  If you can reproduce
such problems with just Jalv, please explain exactly how.

Ah.  With that, the preset you sent works unmodified for me:

$ lv2info http://guitarix.sourceforge.net/plugins/gx_amp#GUITARIX
[...]
	Presets: 
	         ampeg

It shows up in the menu in Jalv and restores successfully.

-dr

P.S. Turns out I lied about lv2info listing them by URI
