In short, these strings are worth every penny. They have an amazing tone and their low tension (compared to other flat wounds I've tried) make them incredibly comfortable to play.

Are they expensive- yes. Will they have you questioning your financial rationale- yes. Are they actually better than other flatwound strings for double the price- yes. These feel like flatwounds that are first cousins with round wounds. They're not too dubby or dead sounding but are still super warm like flatwounds are supposed to be. If you're on the fence, just do it.

After much consideratio I purchase a set and put them on my Stingray HH4 WOW!! I love the tone and feel of these string can't go wrong these worth the money

I can't say enough good things about these strings. I bought a set in January 2018 and they've been on my Squier VM Fretless Jazz since then (save for two months where I tried some other strings).

These strings have such a smooth tone and feel. They slot perfectly into the mix at church and they offer a variety of tones with knob adjustments on my bass. They feel outstanding under my plucking hand and they sound great with a pick.

10/10 would recommend these strings. I'll get a set for my next bass, too, whenever that happens.

Recently 'assembled' a Jazz bass- picked up Seymour Duncan Apollo pups... decided TI Jazz flats would be the best fit for this bass! I've heard much about TI's... hoping I get long life from them. Tone is excellent!!
