Initial impression is very good as these look quality. I strung my Dingwall ABZ5 leaving the B string on (Newtone nickel) & these have a really nice feel to them & a finer wind than the Newtone. Nice brightness but not overly so & the tension also feels good on my extra long scale, unfortunately the E string is about 17mm short of the nut, so I've made a temp shim. Andrew said these were long scale (not super).
Tested them amplified at rehearsal yesterday & I think they are maybe the nicest nickels I've tried in a long time (usually use ss).
Like others have said I found no brittleness or harshness, just a lovely solid tone with a bit of crunch when digging in. Tuning stability seems pretty good too as I didn't even stretch beforehand & only needed a couple of minor tune ups during rehearsal.
I will certainly consider these if I choose nickels tho I might see if I can get a single super long E as I don't fancy gigging with the 'shim'.
I'll report back after they've had a fair few hours of play ... thanks against Andrew & D'Addario
