Let me start off by saying that it is a good time to be a bass player! I have used several different brands over the years and lately have been going back and forth between DR and D'Addario. I loved the tone of Sunbeams but the tension was a bit too loose for me in the long run. D'Addarios felt great tension wise and I loved their customer service but something was missing tonally for me.
I talked with Jason at
http://www.bassstringsonline.com and he recommended that I try GHS Boomers. I was resistant to this. Boomers? No, they die fast and I continued trying other sets. After continuously not finding what I was wanting I finally tried a set of the Boomers and loved them instantly. They were put on about a month ago and are still going strong. I've been trying other strings from GHS as well and I have to say that I am a fan of their product as well as their customer service.
My thoughts on...
Boomers:
A great nickel plated round wound. Full body tone with a very smooth feel. I can get just about any tone I'm wanting from these.
Pressure Wounds:
Another great string. These are an Alloy52 blend. Really good output and very smooth. A bit stiffer than typical rounds. They sound great on fretted but really great on my fretless. They are very mid forward but still have a little brightness to them.
Progressives:
These are my hands down favorite string. Especially for a 5 string bass! Circle K has a great B string and in my experience the Progressives B rivals if not beats it. Amazing feel and tone. Also made of Alloy52 from what I understand. Again, very smooth and killer tone.
Haven't tried anything else yet, but so far I love what I've tried!
