Sigh ... I really need a new set of strings. The EB's that I have right now (STHB 10-52) are not staying in tune properly. I play around 6 hrs per day, at random intervals. I have these strings on a PRS 25th Edition Custom SE, and since it has a tremolo system, try to keep it at standard tuning when I put it away. However, when I pick it up later in the day, the D and G strings go right off, with G dropping to F# and D to a very flat D. I've used EB's on my 7 string before, and they didn't sound as good, however, after some time, these have started to sound good as well. I'd like to try another set and *hopefully* get a good experience out of EB strings. Are there any that you guys recommend? BTW, I play mostly death metal songs, like early Opeth and Death style, as well as some A7X and Epica.
