I must say that I really like Cobalts. I have no idea how they work with splits and have yet to find any of the split coil sounds, on any of my split coil switchable guitars, to be sonically remarkable. None of them sound anything like a strat or tele, to my ear, and I almost always play them "full humbucking". For instance, my Ibanez goldtop SX320 with Ibanez/Duncan humbuckers sounds incredible with the control on "full humbucking", but unimpressive split. Otherwise a great guitar.
I find Cobalts to produce a strong and beautiful sound on all the guitars I have put them on. I also use regular D'addario or EB 0.009"s.
About a half an hour ago I put a set of Cobalt nines on my new Santana SE in Santana yellow and they sound very good.
Note: How do you like the stock "HFS/VB" pickups? What will you replace them with?
I have a PRS SE Standard that the previous owner installed a Seymour Duncan "JB" pickup at the bridge. I don't mind the JB pickup and have them in several guitars, but I might put the stock bridge that came along with the guitar back in because I tend to like stock SE pickups. Do you happen to know what the stock pickups were in the PRS SE Standard? It is a cool guitar and the one in my avatar. I can use the JB elsewhere with no problem. How are the stock SE Standard pickups generally accepted by the crew?
