I bought 2 of these for my Traben Neo 4 which I was respraying and adding some upgrades on, I bought these as they were all I could afford at the time and I just wanted to get the job done. Once the bass was built and set up I was shocked. These pickups gave an amazing warm and clear sound (no hum or muffled sound) they give both great tone and deep bass, I would highly recommend these overall, I used 1 for the bridge and one for the neck, paired this with a pickup blender control knob and your classic 4 knobs for tone, mid, bass and volume. The only con I can think off with these is that I cannot afford to put these on all of my bass guitars!
