Not much interest here on TB but a lot of variations available online. I am using: D'Addario Nickel Half Round on 1966 Gibson EB2D D'Addario SS Half Rounds 50-105 on 1995 Fender P with SD P+J SIT Silencers - Half Rounds on Squier Affinity 5 + Alembic Essence 5 D'Addario Bronze but changing to SIT Silencers on Fender Kingman ABG And have 50-105 Chromes waiting for MIA Precision to arrive. The end result is that I the clarity, tone and smoothness to the touch. Am looking forward to trying the Chromes on the MIA Precision.
There are many using GHS Brite Flats on here, I have seen a bit of postings on them. Many are also under the impression they are true flatwounds which is false. All D'Addario HalfRounds are now with Pure Nickel outer windings. They no longer make Stainless ones... SIT Silencers are Pressurewound type Nickel Plated Steel strings while SIT Power Flats are Half-Round type with pure nickel outer windign.
I knew about the SS D'Addario Half Round being discontinued. When I found my P bass in a pawn shop, it was just strung with a new set of SS with the packet still in the case. They sound so good, I can't bring myself to replace them, so I hope they last for years.
I like my Silencers, and since I now have three basses (two with flats) I'm actually thinking about pulling the TI's off my Yamaha and trying some half rounds on it since I've never used them before.
I have nickel D'Addario half rounds on one of my basses. It took them a little longer to "break in/mellow out", but I really dig them! Unique feel and tone. Pretty cool for pick use where you dont want a lot of 'clickiness'.
When I took the EB rounds off my Alembic Essence 5 and fitted the Silencers which I liked on the Affinity 5, the change made me think I had a mismatch. The next day I made a slight change to the EQ to a smile to drop the mids and now I am completely happy with the sound. I bought perhaps 3 packets of strings during my 1st 35 years of playing. Never really knew you had to change them. Over the last 6 years, I have bought perhaps a dozen and started to experiment to unfortunately learn that each instrument is different as are my expectations for each instrument I guess 'cause I have more basses than I ever had before. For most of my time as a bassist, I never had more than 2 at a time and some stayed for many years.
I was never a fan of half-rounds, and I still don't care for the ground type, but I tried a set of compression-wounds (Ken Smith Compressors) on my fretless Ray about a year ago and I really like them. ...never too old to learn something new!
Here's a very informative thread on this; http://www.talkbass.com/forum/f16/search-ultimate-non-round-non-flat-800932/
I'm using Picato Stainless half rounds on my fretless. They are the only stainless half rounds I have managed to find so far in the UK.
