Schecter SLS Evil Twin-4 Satin Black 4-String Electric Bass

Quick Product Summary

The Schecter SLS Evil Twin-4 in Satin Black is a premium four-string electric bass designed for players who want fast modern playability, extensive onboard tone shaping and high-end construction. Its swamp ash body is built around a multi-ply Maple/Walnut/Padauk neck-through design with Ultra Access, while a 34" scale and Thin “C” profile maintain a familiar four-string feel.

Dual Fishman Fluence Bass Soapbar pickups provide a remarkably broad tonal palette, with Classic, Funk and Modern voicings, pickup blending, single-coil switching and an active 2-band EQ all available directly from the instrument. An ebony fingerboard with 24 X-Jumbo stainless-steel frets, Grover tuners and a versatile string-through or top-load bridge complete a serious performance bass for stage, studio and demanding everyday use.

What Makes the Schecter SLS Evil Twin-4 Special?

The SLS Evil Twin-4 combines premium construction with a particularly streamlined playing feel. Its Maple/Walnut/Padauk multi-ply neck runs continuously through the swamp ash body and incorporates carbon-fibre reinforcement rods for additional stability. Schecter’s Thin “C” profile measures approximately 20mm at the first fret and 22mm at the twelfth, while the flat 16" radius ebony fingerboard and 24 X-Jumbo stainless-steel frets provide a smooth, precise surface for everything from traditional bass lines to fast technical playing.

Its Fishman electronics are a major part of the appeal. The two Fishman Fluence Bass Soapbar pickups offer three selectable voices – Classic, Funk and Modern – alongside pickup blending, a push/pull single-coil function and active bass and treble EQ. This gives the SLS Evil Twin-4 the flexibility to move from warmer traditional bass sounds through to articulate, aggressive contemporary tones without relying on external processing.

Who Is It For?

The Schecter SLS Evil Twin-4 is particularly well suited to intermediate, advanced and professional bassists who want a premium four-string with modern construction and extensive tonal control.

Its combination of Fishman electronics, stainless-steel frets and fast neck makes it particularly capable for rock, metal, progressive music, funk, fusion, alternative styles, recording and live performance, while the familiar 34" scale makes it accessible to players moving from a conventional four-string bass.

Why Choose A Multi-Voice Active Bass?

A conventional passive bass often provides a strong core tone with relatively simple onboard adjustment. An active multi-voice instrument offers considerably more control before the signal even reaches an amplifier or pedalboard.

The SLS Evil Twin-4 provides three fundamental pickup voicings alongside active EQ and pickup blending, allowing the instrument to adapt quickly to different songs, amplifiers and playing techniques. This can be particularly useful for session musicians, covers players and bassists who need several distinct sounds during a single performance.

How Does It Compare?

Compared With A Traditional Passive 4-String

A traditional passive bass typically prioritises simplicity, with basic volume and tone controls. The SLS Evil Twin-4 adds multi-voice Fishman pickups, active EQ, pickup blending and single-coil switching, making it significantly more flexible for players who want to shape their sound directly from the instrument.

Compared With The SLS Evil Twin-5

The four-string version uses a familiar 34" scale and traditional four-string range, while the five-string model extends to a 35" scale and adds a low B string. The SLS Evil Twin-4 is therefore the more natural choice for players who prefer conventional four-string spacing and range while retaining the premium SLS specification.

Frequently Asked Questions

Is the Schecter SLS Evil Twin-4 an active bass?

What pickups are fitted?

The bass features two Fishman Fluence Bass Soapbar pickups, one in the bridge position and one at the neck.

What are the three Fishman voicings?

The three-way voicing switch provides Classic, Funk and Modern settings, allowing the fundamental character of the pickups to be changed quickly.

Does it have a single-coil mode?

Yes. The master volume incorporates a push/pull single-coil function, providing another tonal variation alongside the three main voicings.

What does the active EQ control?

The onboard Fishman 2-band EQ provides bass and treble adjustment, allowing the frequency balance to be shaped directly from the instrument.

Is the bass neck-through?

Yes. The multi-ply neck runs continuously through the body and incorporates Schecter Ultra Access shaping for comfortable reach to all 24 frets.

What is the advantage of neck-through construction?

Neck-through construction removes the conventional bolt-on or set-neck joint at the body, allowing a particularly smooth transition into the upper register while creating a rigid continuous structure through the instrument.

Does it have stainless-steel frets?

Yes. The SLS Evil Twin-4 features 24 X-Jumbo stainless-steel frets, offering a smooth playing feel and excellent resistance to long-term fret wear.

Yes. Its articulate Fishman electronics, fast neck and modern construction make it particularly well suited to rock, metal and progressive music. Its multiple voicings also make it versatile enough for many less aggressive styles.

Can it produce more traditional bass sounds?

Yes. The Classic voicing, pickup blend and onboard EQ provide plenty of scope for warmer, more conventional bass tones as well as modern sounds.

Can the strings be top-loaded?

Yes. The Schecter Custom Bass bridge allows the strings to be installed either through the body or directly through the bridge.

What tuners are fitted?
