I bought these mics to change my old pickups mm (they were original and had a serious problem of low frequencies, which is a shame for a bass). It's been 1 month 1 / 2 that I play with those they love and the crystalline clarity of notes, trs rponse Fidler in the bass and treble with midrange trs typs " precision. " They happily resituent harmonics.
Only default (and still is not serious trs): They have an output level not trs lev ncessite therefore gain a little harder to pramp. Otherwise they are pretty passive pickups!
