Just put new strings on the HD28. First time I've had anything but elixirs on an acoustic in at least a decade. I've gone for Martin SP Lifespan 12-54's, on the assumption that Martin's own strings are a good place to start. I also have a set of EB Paradigms to fit next, once these start sounding dead.
At the risk of sounding naff, but mostly so I don't forget, I want to write this down as I go along so I can't look back at past posts and read what I thought at the time of fitting each set. Happy to have input from anyone else who's done similar too!
Onto the strings... these SPs are a bit fuller than the Elixir 1's I had on until today, but also compared with the set of Elixir 12's I had before that, but also have a good bit of sparkle which I'm desperately hoping won't fade after 2 hours! They feel a little less slippery, but not drastically so, so I'll get used to them within a day or two. Will wait and see how long they last; I'd generally get 3 months from Elixirs, so if these are still here come Christmas I'll be a happy camper.
