Several weeks ago Jason at BassStringsOnline.com let it slip that there was a brand new set of low tension flatwounds coming out from a company he couldn’t reveal. He made a few sets available on a pre-order and I got mine a couple of days ago….still anonymous in plain packaging. I posted this review in another thread that I guess is dead now so re-posting it here. I've never seen the burgundy silk this set sports so no clue there as to who made them. No silk at the ball ends. The gauges are: 100, 069, 055, 040. My first sonic impression stringing them was that brand new and unstretched they were similar in tone to the three month old TI Jazz flats that had been on this bass (a new 63 AVRI Precision). Next was the obvious similarity in tension and mass to the TI Jazz set....no truss rod or major intonation changes necessary. There are some very fundamental differences though and you'd never mistake these for TIs. I want to say La Bellas but I really don't know. They have the same very slightly grabby touch (that goes away with playing) and the core has the same solid slightly un-giving feel of the much heavier La Bella set I've used fairly recently. It's also obvious that over time these strings will give a much more traditional thuddy flat wound sound than even a several year old set of TIs ever will. I love the TIs like no other string but I have them on other instruments and truth is for this bass they have felt a little too loose at times. It doesn't feel like these strings have much more tension but they do have a slightly (but very noticeably) stiffer feel. Whatever the heck they are they might be a good match for this instrument and I'll be leaving them on for a while to see how they break in. Fast forward another 24 hrs and I've gotten maybe 5 hours playing on them. One thing that stands out is that unlike some flats that have a really annoying initial metallic clang that can take weeks to completely fade these strings are immediately very smooth and even sounding....very pleasing. While they are definitely a traditional sounding flat and will no doubt loose some high end ping (as they already have) there's nothing that makes them unplayable for me right now. Also the grabbiness I described when I first put them on is completely gone. It's impossible to really judge any flat until it has a chance to break in over several weeks at least but I would say that anyone who likes the low tension of TIs but is looking for a more traditional feeling and sounding flat might want to have a look at this set. So far I'm pretty impressed.
