BB2004, BB2005 specifications

The Yamaha BB2005 and BB2004 bass guitars stand out in the world of electric bass instruments, combining classic designs with modern innovations to meet the needs of today's musicians. Both models are part of Yamaha's BB series, which is renowned for its comfortable playability, rich tonal characteristics, and versatile performance capabilities.

The BB2005 features a five-string configuration, while the BB2004 is a four-string model. This distinction allows bassists to choose based on their playing style and musical requirements. The BB2005 opens up a broader tonal palette, perfect for genres that demand extended range and deeper bass notes, while the BB2004 continues to be a favorite among traditionalists who appreciate the classic sound of a four-string bass.

One of the key features of both models is the solid mahogany body, which contributes to a warm and resonant tone. The combination of a lightweight design and contoured edges ensures comfort for long playing sessions, making these basses not only sound great but also easy to handle on stage or in the studio.

Equipped with Yamaha's custom-designed pickups, the BB2005 and BB2004 deliver powerful sound output. The single-coil and humbucker configurations offer a diverse range of tones, allowing musicians to shape their sound with precision. This feature is especially beneficial for players who seek tonal versatility, as it accommodates everything from smooth jazz lines to aggressive rock riffs.

Additionally, both models sport a 34-inch scale length, which provides a balanced feel and makes fretting notes easier, especially for lower strings. The necks of the BB2005 and BB2004 are crafted from maple with a rosewood fingerboard, enhancing sustain and clarity. The slim taper profile allows for fast playability, appealing to bass players who value speed and agility.

The BB series also incorporates a vintage-style bridge that improves string vibration transfer to the body, resulting in enhanced resonance and sustain. The aesthetic appeal of these basses is strong, featuring a choice of striking finishes that highlight the natural wood grain.

Ultimately, the Yamaha BB2005 and BB2004 are characterized by their exceptional craftsmanship, versatility, and modern performance features. These bass guitars cater to a wide audience of players, from beginners to seasoned professionals, who demand quality and reliability. With their rich tones and user-friendly design, they continue to be a top choice for musicians across various genres, making them a staple in the world of electric bass instrumentation.
