Review: Second to None, Best of the Best - Short version: These strings are incredible. Why haven't you bought them yet? Long version: Oh my goodness, wow. I absolutely love these strings. I even love how they have red cloth wrapping on the end of the string up by the headstock. The tone of these strings? To die for. These are the best bass strings I have ever used. Tone: Some words to describe the tone are as follows: biting, growling, aggressive, articulate, and bright. These strings were made for players who want to be heard, who want to cut through the mix. These strings have great low end, but that's not the impressive part. What's so impressive about these strings is that when a note is played, the combination of midrange and high harmonics give the tone a metallic, almost piano-like quality. Good for slap bass? Goodness yes. Versatility: These strings may be bright and audacious, but they can also be tamed by simply turning down the tone knob on the bass. They will never be as mellow as flatwound strings, but they definitely create a more subdued, smooth sound when the tone is rolled off. Because of this, they are incredibly versatile. They can be used to produce both articulate, biting tones that can cut through the mix and tones that will put the bass in the background. Drawbacks: If you are a sloppy player, or a beginner, these strings may not be for you. They demand a very precise player, as every fret buzz, wrong note, and finger slide (that "eek" noise when the finger is moved along the string) will be accentuated. That being said, these strings will teach you to play with more accuracy. Some people say these strings are rough, but I don't think they feel any rougher than other brands of strings. That being said, like all roundwound strings, these will eat frets and fretboard wood over time. I recommend using these strings on a bass with medium jumbo or jumbo frets for the sake of longevity. Also, don't even think about putting these on a fretless; they will absolutely destroy the wood (but that is true of all roundwound strings). Conclusion: Buy them. The pros of these strings are so incredible that the cons don't really even matter. I will be singing the praise of Rotosound strings until they stop selling them, or until I die. Hopefully the second option happens first. Review: Love these. - I've been playing bass since the late 80s, guitar since the late 70s. I suppose I've been through most types of mainstream bass strings during that time. I've always wanted to try a set of Rotosound round wounds. Every time I'd think about buying a set, I'd read some reviews. You hear the same thing over and over no matter where you go looking. "Sound great but too rough, too much finger noise, killing my fingers and eating my frets"... You'd think your fingers would be rubbed raw and your frets worn through to the wood before they lost the new string zing! I finally bought a set and put them on a PJ bass. These stings are fantastic! I've been an avid DR stainless (and nickel) Lo Rider user. GHS boomers and D'Addario balanced nickels too. These are similar, but have somthign more. I think more aggressive lower mids and smoother highs. All in all just more balls. The feel too. The outer windings are a larger diameter than most other strings, like the DRs and GHS boomers etc. You'd think that would be a negative, maybe it is for many, but for me it's a surprising improvement. I actually find finger noise reduced and they seem to have less clank. My fingers have decent callouses, so I don't find them hurting me at all. Wish I'd tried them sooner. Fret wear? Time will tell, but I've had stainless strings on at least one bass for a long while. No issues and I don't see how these would be any different. ## Features - STAINLESS STEEL 45 65 85 105 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002CVUNMA | | Best Sellers Rank | #3,285 in Musical Instruments ( See Top 100 in Musical Instruments ) #18 in Bass Guitar Strings | | Brand | ROTOSOUND | | Brand Name | ROTOSOUND | | Coating Description | No coating | | Color | Silver | | Customer Reviews | 4.8 out of 5 stars 905 Reviews | | Finish Type | Uncoated | | Global Trade Identification Number | 00686194000134 | | Instrument | Base | | Item Type Name | Bass Guitar Strings | | Item Weight | 10 Grams | | Manufacturer | RotoSound | | Manufacturer Part Number | RS66LF | | Material Type | Stainless Steel | | Model Name | Swing Bass 66 | | Model Number | RS66LF | | Recommended Uses For Product | General use in playing bass guitar in various musical styles | | String Gauge | Medium | | String Material Type | Stainless Steel | | UPC | 686194000134 400033807605 | | Warranty Description | Free from defects. | ## Product Details - **Brand:** ROTOSOUND - **Color:** Silver - **Instrument:** Base - **String Gauge:** Medium - **String Material Type:** Stainless Steel ## Images ![RS66LF Swing Bass 66 Stainless Steel Bass Guitar Strings (45 65 85 105) - Image 1](https://m.media-amazon.com/images/I/81ktTzSbG+L.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Second to None, Best of the Best *by A***D on June 6, 2013* Short version: These strings are incredible.

If you are a serious bass player, then you should know that these really don't need an introduction (you know the pros that play(ed) them, such as Squire and Entwhistle who were not afraid to cut through the mix). If you haven't tried them at least once, you should, especially considering the competitive price (I'm really surprised that they don't cost quite a bit more, considering their quality, popularity, and the vast list of highly-regarded pros that use them). They may be too bright, pronounced, and hard on the fingers for some, but if you try them and like what they offer, chances are that you, like many, will never go back to any other strings. Also, if you are not satisfied with your sound through your current amp and/or pickups and are considering spending considerable money to upgrade, you may wish to try this less expensive "upgrade" first. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1772187-rs66lf-swing-bass-66-stainless-steel-bass-guitar-strings-45](https://www.desertcart.us/products/1772187-rs66lf-swing-bass-66-stainless-steel-bass-guitar-strings-45) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-17*
