Hello Jean Michel, I posted 3 jpg's of the Pasacalles por la E by Murcia in the "Photos" section of this webpage.
Saludos

Dear Jean Michel, I use a bourdon in the 4th course. The most probable Murcia's stringing includes a thin g placed up in the 3rd course (together with the normal G). I could never use that stringing in my guitar because it is too long and the string would break, but I had to change several fingerings of "campanela" scales to solve the problem. I would suggest you to put the thin g also. I will, no sooner I have my new spanish baroque guitar built (by Sebastian Nuñez).
Saludos
