I don't see a lot of threads on the 5655s, are they not a popular model? One thing I saw a lot of is that they're higher output, and more of a "rock" guitar, neither of which I have a problem with. I also put on 12-56 Cobalt with a wound third, both because my hands are huge and have the strength for it (I suppose this matters more to the 55-110 Cobalts on my bass), but also because they're higher output, which goes along with the guitar. To that same thought, I don't see a lot of talk about Cobalts in here. For as much as I hear the bass strings complained about because they're "bright" (even though they actually get more of an increase at the low end than the high end), I'd expect them to be popular for what is typically thought of as a Gretsch sound. Will I run into any problems using strings that heavy? Other than them being so short that they can barely wrap around the peg, not sure if Ernie Ball is trying to save money on metal, but I don't remember this issue on my strat with a longer scale. Obligatory "pet tax" attached. Yes, my band plays Palaye Royale covers, no, I didn't copy the look of Sebastian's guitar intentionally.
