GHS Boomers were the first replacement strings I ever bought when I first started out playing! I wanted new strings for my GTX bass, this would have been 1992 or so, went to the local store knowing nothing and saw 'BOOMERS'! Figured they had to be good
Over the last few years I've become really serious about strings, and after discovering custom sets and balanced sets this really revolutionized and improved my playing.
I've gone through most every GHS string set they offer upon my string quest, and I'm currently using a set of Precision Flats on my 5 string Spector which is something I NEVER thought would happen! But around here, acoustic gigs have become the hot thing and these strings on this bass are a phenomenal setup to go with acoustic guitars.
Since we're being honest here, I'll present the reasons I don't use other GHS strings anymore.
The main reason is the price for singles. GHS singles are for some reason super expensive compared to their packaged sets, and other brands singles. For instance, I think Progressives are great strings..but I don't like the pre-packaged sets for two reasons. Firstly, on the 4 string sets they package them with a shorter E string than all the other strings. It's not long enough to work on my Warwick so I have to buy a separate E string which makes a set of strings around $28 for a 4 string. I like them, but I don't like them that much. And, it's no cheaper to build a custom set thanks to their premium pricing of singles.
I also wish the Progressives were available fully wound instead of contact core. I just don't care for contact cores.
So, I was completely ready to order a custom set of lighter gauge Boomers (from Bass Strings Online, of course!) with the .135...only to find out they no longer make a .135! BAH! No Boomers for me then. Thought about Progressives on it, but I really don't want the contact cores, and they cost more...plus the premium upcharge for ordering singles. Just can't see paying $40 plus shipping for set of strings. BAH!
