Ghs Boomers are great for Alembics they have great mids and great low end, to me they sound massive. Elixir is also great because it?s the same string with coating. Try to record something on tape and then compare to other strings. It?s also good to know that when you buy a set of 45-105 some strings feels really stiff and some other smooth, one of the reasons is that not all 45\s are 45\s some are actually 44 or43 you know it feels smoother and are better for you but actually the thing is that you by thinner strings. Please record with different strings in same gauge and you notice the difference.
Strings also sound different depending on the distance between tuners and ?string holder? (where the string starts from in the body of the bass, hope you know what I mean) the longer the difference is tighter the string gets, it also usually sounds better or actually its better to say rings longer. (Now we are only talking about 34\basses). I used to use Boomers on my Fender but they did not work too well, but once I did put them on my Alembics it was just perfect. Alembic basses have so much high end that I do not need any more from my strings. Boomers has high end too. ?Just what?s needed for my Alembics?
All The Best,
