Thanks for your help Harry, well it is indeed a mess with those LV2 
preset behavior.
Indeed jalv save presets correct, but the resulting preset is missing a 
label

when I add per hand to the file
<http://guitarix.sourceforge.net/plugins/gx_amp#GUITARIX#default>

the preset works.

Ardour3, saves the preset after some times trying correct. Mostly when 
the session is quit, in the next started session load the preset (which 
makes it half the way, and press save some times.
The result is a functional preset.

Umpf,
