Review: Get the "Geddy Lee" growl sound. - Love Rotosound, been using them on all my Jazz bases. They stay bright for a long time and helps get that "Geddy Lee" growl tone. Wouldn't use any other bass strings. These are top and their prices have came down over the years.
Review: For a Rickenbacker 4003w, my favorite so far - I have been struggling with my Rickenbacker 4003w for a while now, just couldn't get the action and neck relief just right. Saw a video on Youtube where the gent spoke about running a super light set of strings on ricks...soooo. I am so happy that I tried these. I had to adjust the neck a hair, but now the action is low, the intonation is better, and you can bend the strings super easy. One adjustment I found was my left hand technique, these strings require a lighter touch, like a MUCH lighter touch...if I push on them like I would any other bass I fret buzz like crazy, but lighten the touch and no buzz. After playing for 25+ years this is a first for me.

### ⭐⭐⭐⭐⭐ The first and still the best bass strings for me.
*by B***O on September 13, 2019*

I have played bass for over 50 years. I started using the RS66's in the 60's. I play guitar and mandolin as well, and for the last 3 years I had no bass gigs. Now I do. I have some weakness in my right arm and saw that RS makes a medium-light gauge (.90 low E) and decided to try them, they sound just as good and, after adjusting my bridge for the lighter gauge, they play perfectly and sound great. It was a YouTube clip with Chris Squire that made me investigate the other gauges. He used the original gauge but his hands are incredibly huge. So I'm a big fan of RS and the fact they have created a lot of different gauges while keeping that sound.
