Build Quality & Aesthetics

The craftsmanship is excellent, which is no surprise from APC, a brand known for its hand-built instruments made in Portugal. The solid spruce top gives the instrument a crisp look and a bit of extra tonal brightness, while the walnut back and sides offer warm, woody character.

The satin finish is smooth and natural, enhancing both comfort and the wood’s visual texture. The uke is lightweight but solidly constructed, with a well-fitted neck joint and tidy fretwork. It’s a refined instrument without being flashy—understated, elegant, and clearly built by experienced hands.

Sound & Performance

Unplugged, the APC UKU Bass S delivers surprising volume and warmth for its size, although the low-end is naturally softer than a full-sized acoustic bass. It’s more of a practice or writing tool when used acoustically.

Plugged in, however, is where this instrument comes alive. The built-in APC preamp system includes a 3-band EQ and a digital tuner, making it gig-ready and versatile. When amplified, you get a rounded, upright bass-style tone with plenty of thump and definition. Perfect for acoustic gigs, home recording, or intimate jam sessions.

The rubbery polyurethane strings take a bit of adjustment if you’re used to metal-wound bass strings, but they’re gentle on the fingers and great for warm, percussive playing.

Playability

The short scale and uke-style body make this incredibly comfortable to hold and easy to play, even for extended sessions. The neck is wider than a standard ukulele but narrower than a traditional bass, which strikes a nice balance.

• Excellent craftsmanship from a respected luthier

• Compact and lightweight

• Warm, upright-style bass tone when amplified

• Built-in EQ and tuner

• Ideal for travel, acoustic gigs, or home use

The APC UKU Bass S Electro-Acoustic is a refined, elegant, and sonically charming option in the bass ukulele world. It’s more than a novelty—this is a real player’s instrument with the tonal warmth and build quality you'd expect from a traditional luthier. Ideal for acoustic gigs, songwriting, or low-volume practice, it offers a rich, organic tone in an ultra-portable package.
