These are Long Scale Strings, the 'Black Nylon Trubass' string was originally developed for the Burn's Black Bison Bass. Great Strings to simulate a double bass sound on an standard bass guitar.You will note that the tension is low, making this string extremely comfortable to play and the heavier gauge is due to anything lighter and the strings themselves would start to flap.

Particularly good on fretless bass (but also well-suited for jazz, dub, and reggae on fretted instruments), the Tru Bass 88 black nylon tapewound bass strings can be heard on such famous albums as the Beatles' Abbey Road and Lou Reed's Transformer. Tonally, the sound is similar to that of an acoustic upright bass, with a smooth feel and extremely low tension.

Ranges from 65-115 gauge.
