GHS pressurewounds were my first adventure into roundwound strings. They were good but I wanted a little more bite to my sound. I have since moved on to Nickel Lo-Riders and have been fairly happy with the sound, feel and tension. I recently just found a brand new set of GHS Boomer 52 strings in my desk drawer from over 5 years ago and put them on one of my 4 strings and I'm really liking the extra punch and sound of what alloy 52 strings bring to the bass. Unfortunately they are no longer made. I'd like to try an alloy 52 string on my 5 string Stringray and it seems that the GHS Progressives are the most comparable to what the Boomer 52 sound is. However, I'm not sure about the exposed core the B and E string and from doing research, I'm seeing a mixed reaction to how people like it. Currently there isn't a non-tapered B string available for the Progressives. I'm looking for suggestions for a good alloy 52 string set preferably with a non-tapered B string. Or if someone wants to speak to how they find a tapered B string, that would also be helpful. NOTE: I have been searching through the forum and a lot of the threads are a few years old and it seems that some of the products are no longer available.
