I bought a bass that had extremely bad dead spots at the 8th, 9th, and 10th frets on the D string. Adding (a lot of) weight to the headstock moved the problem to around the 5th fret on the A string. I decided to try removing weight and started with replacing the tuners with these. I went with the short stems to get the lightest set. Of course the tuners look and feel great, but they also did reduce the dead spots (now back at the 9th fret on D). When I say “dead spot” I mean there is an initial attack followed by a rapid drop in volume. These tuners slowed the drop in volume (watching on a VU meter). For those interested, replacing the bridge with a carbon fiber and titanium bridge along with going to 40-100 strings seems to have done the trick. If you need to reduce weight for any reason these are great tuners. They were also drop in replacements for me (Ken Smith Burner bass tuners).
