I bought these to place on a Squier VM 70's jazz. I bought it used and it had Roto flats. Which sounded and felt good. But the tension just too much to play long sets on. I read other reviews and took a chance. Followed specific install directions from EB. Immediately I noticed a nice punch and clarity. Nice string balance and they felt great. Tension was perfect more on the low side, not TI's low I would say comparable to labella LTF's. Both which I have on other basses. I can't wait to play these in a band setting. Also great slap tone. Very impressed with these.
