Perfect strings for Rockabilly, Bluegrass, Psychobilly, Country/Western, and more!

Fits most 1/2, 5/8, 3/4, 7/8, and 4/4 scale basses.

6 string options included in every pack. .170, .155, .130, .105, .095, .080 (sizes in inches)

100% "synthetic gut" – nylon/kevlar construction to simulate the tone and feel of natural gut strings.

Please read the full item description below for even more information about this product.


Simulated “gut” texture on full length of strings. The strings have a light to medium-soft texture that has been "spiral cut" into the string. This slight texture facilitates better gripping of the strings for lightning fast pizzicato playing, and drag triplets with with almost no effort. The strings "grab" the air and force it to move, producing more mid and low end tone when playing acoustically.


All of our nylon string sets come as a 6 string “bump” assortment (6 total strings of various gauge. See photos.) for 1/2, 3/4, and 4/4 size double bass. The idea is that some players prefer thinner, lower tension strings while others prefer thicker, higher tension stings. Why not offer a wide array of thickness and tension all in one package of strings? This is exactly what we do!


Our string sets also include rubber dipped metal ends. NO KNOTS to come untied in the middle of your set! We are proud to be the only company offering this configuration. You need strings that sound great when played acoustic or amplified, strings that won't tear your fingers up if you need to play 3 sets in one night, strings that stay in tune in hot/cold/humid/dry climates. You need Superior Bassworks Kevlar cored nylon strings for double bass.


Perfect for Rockabilly, Psychobilly, Bluegrass, Country/Western,and much much more! The string sizes included in each pack are: .170, .155, .130, .105, .095, .080 (sizes in inches). If your bass has never had non-steel strings installed, please keep in mind that some modification of the tailpiece string slots, bridge string notches, nut string notches, and tuning machine string holes may be required. This is completely normal, and will not prevent you from switching to other string types in the future. Please measure your bass before ordering. If you are not confident making these adjustments yourself, please consult a professional luthier or more experienced bass player for assistance. These strings are not recommended for school orchestra students.

Amazing sustain 5 product stars
"Yorkie here from the Boners,after trying just about every synthetic string on the market i have finally found the right string,i fitted them 3 days before a gig and they were fully stretched on the night,great tone/sustain absolutely love them,i was considering going to steels till i fitted these..no more searching,many thanks."

Great strings !!! 5 product stars
"These are the best "gut-like" strings I've ever played. Most people think these strings are for slappers only, but that's not true at all IMHO. I play pizz only (no slap) and love the old-school sound of these strings. Great for roots, blues, traditional jazz, etc ... Most of the time gut-like strings have a tendency to sound muddy and get lost in the mix. Not so with my SBW Deluxe Dirty Gut set! Great strings for a really affordable price." Nordine Ben-Kabbach - 11/6/2012
Greatest Non-Gut Guts!! 5 product stars
"I've had these on my '38 Kay for a month, and just put them on my '48 as well, and these are some of the best strings I've ever used. Low or high action, these are wonderful, and you can't beat the price!" Jacob Dill - 6/2/2015
AWSOME! 5 product stars

The search is over 5 product stars
"After playing five different sets of strings over the last two years, The search has ended with Superior Gripmax. The tone and sustain is far "Superior" than any other synthetic than I've ever played. The "grip max" feature makes them much more player friendly. Not to mention I like choices, and the "6 string bump" gives me more options right out of the bag. I have played these strings from the U.S., all the way to Europe, and back again." Buford T. with The Psycho Devilles - 11/12/2012
I can not belive these are not GUT! 5 product stars
"Im using the SBW dirty gut DLX and I cant seem to figure out how these are not gut strings. They look like gut.....feel like gut...they sound like gut....its like vegan gut strings...im blown away. These are the last strings ill ever need untill SBW makes another I need." Aaron Harris - 10/24/2012
Play These! 5 product stars
"These are great strings! They put the "wood" back in my bass sound. Nice, earthy, organic, and tight. I've tried other nylon-based strings and they all sounded harsh compared to the Deluxe strings. They're a breeze to play, easy on the hands and fingers, slap nice and smooth, sound like guts, play like guts, and have no string maintenance normally associated with guts. Having 6-strings to choose from makes these the most flexible set of strings on the market. If you want to try guts but are leery of the cost, then look no more. For the price of one gut string you get six American-made "just like gut" strings that will last forever. Thanks Superior Bassworks!" Bob Peirce - 5/13/2012
SBW The Best Strings on the market 5 product stars
"I Have used real guts for a few years and love the fell and sound for Rockabilly and Swing. My guys started to fray really badly so it was time for a new set. i tried a few synthetic brands in both the standard and Pro series, They were terrible. Then i saw the SBW set on the net and thought " well for that price, give them a go" They are unbelievable, with a feel and sound as good as guts. I put them on my second no name bass to try and have just ordered a second set for my main bass (a Christopher) which still has agood set of guts on it. The guts are terrible in my part of the world where we can have up to 99 % humidity in the summer. Brilliant strings. Paul (the Jive Cats)" Paul Jackson - 7/10/2017
Amazing for classical music 5 product stars
"I'm amazed by these strings. I'm a classical musician, and I play a lot of early music, so I'm used to play a lot on gut strings. I find these strings extremely good and satisfying, I could not be happier. If anything, I would love you to make also 5th low strings, so to have a full set of Deluxes on my bass. Congratulations! Here is the link to the review I made on my website: http://www.severianopaoli.com/?p=182&lang=en_US Severiano Paoli" Severiano Paoli - 8/5/2015
So good my even my experienced Luthier thought it was real gut! 5 product stars
"Took my bass to my Luthier the other day to get a new bridge. When he graped the bass and played a few notes, he said my gut strings could use some oil. When I told him those were not real gut but some strings called SBW Deluxe Dirty Gut, he was really amazed! :-) He really thought they felt and sounded like real gut strings! Thank you Brandon for making these awsome strings! I'm pritty sure my search is over. ;-) I played Lenzner all gut strings for a while, but will never regret I gave these strings a chance. So much better! Bjarne (the name of my Luthier) might get in contact with you to here more about your selection of strings. I'll give you my highest recommendations!" Henrik Ørnsholt - 3/30/2013

Get you some!! 5 product stars
"I have been wanting that more traditional sound for years but didn't want to deal with the maintenance or PRICE of gut strings. Well folks here is your answer to that hurdle. Really like the rubber dipped end. Great quality and an EXTREMELY reasonable price!! Get you some!!" John Garza - 5/8/2012
6 Guts for the price of 1! 5 product stars
"My first band practice with my new Superior Bassworks Deluxe strings went very well. I only had them on for one day and they held tune well. These are the best nylon synthetic gut strings I have ever had on my bass. They come in a six string gauge set, I like the middle set myself. For the price you won't find a better nylon string. They still need time to break in but after only one day my bass sounds much better than before. I highly recommend these strings." Jayson Minor - 4/26/2012
