Schecter built the SLS Evil Twin-4 as a neck-through, four-string electric bass positioned within its SLS (Select) line. The instrument was offered in Satin Black and carried construction and hardware choices consistent with a player-focused instrument built for extended technical use, featuring an arched top body of Swamp Ash with ivory single-ply binding and a neck-through-body construction with Ultra Access to the upper register.
The multi-ply Maple, Walnut, and Padauk neck incorporates carbon fiber reinforcement rods and is shaped to a Thin 'C' profile, measuring .787" at the first fret and .866" at the twelfth. It carries a 34" scale ebony fretboard with a 16" radius, 24 X-Jumbo stainless steel frets, Roman numeral inlays, glow-in-the-dark side dot markers, and a 1.496" Graph Tech XL Black Tusq nut. Tuning is handled by Grover Bass 144 Series machines. Both the bridge and neck positions use Fishman Fluence Bass Soapbar pickups, with electronics comprising a Master Volume (with push-pull single-coil switching), a Blend control, a 2-Band Fishman EQ, and a 3-Way Toggle Voicing Switch offering Classic, Funk, and Modern voices. The Schecter Custom Bass bridge accepts either string-through or top-load stringing. All hardware is finished in black, and a 9-volt clip-in battery compartment serves the active electronics. The bass was strung from the factory with Ernie Ball 4-String Super Long #2849 (.045–.105).
Owners requiring setup adjustments, fret work, or parts sourcing for components such as the Fishman Fluence system, Grover 144 Series tuners, or Graph Tech XL Black Tusq nut should consult a qualified bass technician or luthier familiar with active electronics and neck-through construction.
STRAIGHT TALK
What Stands Out
Keep In Mind
From the people who own them
Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.
Owner photos
Put yours on the record.
The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.
What do you know about this one?
Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
