    New Fav!

    I have been using EB strings for quite some time. I've always used the 1148 set on my LP and 1046 set on my Strat. Mostly, I'd go with the regular nickel wound. I've tried a few sets of RPS and Pure Nickel Wound series and I have to say they are all very good strings, but they are not that good for me to stick with them.

    I had the idea of trying out these new strings because the other guitar player, who plays an SG, in my band sounds so much brighter and more present than me and we were using the exact same rigs. I knew they claim the Cobalt series would give more output and make the sound brighter so I thought I'd give it a try.

    I ordered only one set because this is almost twice the price of the normal EB sets to try it out. The first impression is that the lower 3 strings provides more friction to the left hand than the regular EBs do, which is great for me. This is even better when I got on the stage because my hands sweat. I used to like the sound of a set of new strings but it would take a couple of days for the string to get comfortable to play. The Cobalt provides the great feel straight out of the box.

    As far as the tone goes, there's absolutely nothing wrong with it! It does seems to provide a little higher output. The tension seems to be a little greater than that of the regular EBs with the same gauge. But I do find that it's gradually losing its tension after 2-3 weeks of playing (which is quite normal). The string last quite long.

    I ordered 5 packs from Sweetwater after I tried the set. Will stick with these for some time!

    My new strings!

    Strung my guitar and didn’t notice a huge difference acoustically. When I plugged in I was very happy. These strings do what they claim. They add great focus and clarity. I had some issues with low end “Mud” but not anymore. They sound great, play great and have great tuning stability. If your trying to clear up your low end give these a try. Changing strings is easier, and cheaper, than hunting for new pick-ups, guitars or amps.

    Amazing!

    These are my new go to guitar strings. I play in C tuning, and these tones really help give those lower notes clarity and punch. These strings almost give the guitar tone a compressed sound. Would recommend to anyone.

    So far, so good

    I wanted to dedicate one of my guitars to lower tunings, and the Power Slinky's fit the bill. I can tune down to Drop C tuning and still keep stability and tone at a premium, and still have the ability to bend and play with comfort. I didn't want a super high gauge, and with these, I'm happy so far. Still getting used to them on this guitar.

    Initial Impressions

    I tried the Cobalt Slinkys .011 - .048's on a Gretsch with a Bigsby through a Fender Blues Jr and also on a Swart AST .

    The sound really was different from the regular EB's . Definitely louder, perhaps harmonically richer, seemed to have a bit more clarity but I didn't set up a science experiment to confirm.

    The feel is different too. Especially on the wound strings. It didn't take too long to get used to and in time I may come to prefer it .

    I'm looking forward to trying them on my other electrics and seeing how long the life span is. It was worth the price just to satisfy my curiosity about them and I expect to continue using them.

    Cobalts did not live up to hype

    On a LP, GHS Burnished Nickel Rockers (BNR) .011s are my favorite strings (my gold standard).
    On a Strat I use the GHS EJ Nickel Rockers in .011s.

    IMO the both the BNRs and EJNRs feel better, play better, and sound better than the Cobalts. Note that both of these Nickel Rocker models are somewhat flat-wound on the wound strings.

    To be fair the Cobalts tuned up quickly and have stayed in tune, and have better than average life cycle. I play blues and rock, and some country and jazz, and do a lot of bending — the Cobalts stay in tune. That being said, having tried the Cobalt Power Slinkys on both my Strat and Les Paul I'm not loving them enough to switch.

    -- While my Sweetwater sales engineer can get the Burnished Nickel Rockers, I wish Sweetwater stocked them. --
