Roscoe builds 4, 5, 6, 7 and 8 string electric bass guitars entirely by hand and entirely in their own factory, none of manufacturing is sent out. Even the fine high-gloss and hand rubbed oil finishes are applied in the factory. Raw lumber comes in and finished instruments go out.

Roscoe Basses are available in four styles:

• The LG model is a small hand-carved body offered for 4, 5, and 6 string basses.
• The SKB model is a larger hand-carved body for 5, 6, 7 and 8 string basses.
• The Century Bass with a larger, flat body with extended upper horn available in 4, 5, 6, and 7 string models.
• The Century Signature Bass is similar to the Century but has a carved top and wedge neck and is also available in 4, 5, 6, and 7 string models.

Seven string basses can be strung either high F or low F#.

Eight string basses can be strung with either low B / high Bb or low F# / high F.
