i received my first set of j-roques a few weeks ago.. i was thinking about getting a full set of gamut pistoy or j-roques.. i didnt had the chance to try the sets so i had to decide out of my stomach.. i had a D and G wrap on my bass i bought used before with which i was really happy.. in the end i went with a set of j-roques bec the pistoys would have been 800 euro and 600 for the j-roques is already a lot of money.. blabla..
to cut a long story short..
j-roques - best strings i have ever played! the strings are really thick, nearly as thick as plain gut but they have a nice sustain and speak up the whole fingerboard on ALL four strings.. the feel of them to my fingers is perfect.. i need less power and get more tone out of my bass with these strings.. and they sound fat fat fat fat and still perfectly clear on the whole range on ALL strings..
i cant comment on arco as i am not much of an arco player, but i have no problem bowing them..
btw.. the D and G string from the j-roque set is very different compared to the D and G wrap.. i prefer the j-roque D and G..
