Yamaha 4 String Bass Guitar TRBX304 BL - Balanced Mahogany Tone

Our review of the Yamaha 4 String Bass Guitar TRBX304 BL finds it best suited to gigging players and serious hobbyists who want a versatile, stage-ready electric bass without spending into the upper tier. The single biggest reason to buy is the combination of a solid mahogany body and active Performance EQ, which together deliver rich low end and a wide palette of usable tones for slap, pick, flat, finger and solo styles right out of the case. It presents as a well-built instrument that prioritizes playability and tonal flexibility.

Key Features

• Five-Piece Maple/Mahogany Neck: Adds stability and a comfortable feel for extended playing sessions and reliable tuning across gigs.
• Active Electronics: Give immediate control over the instrument's voice with more output and dynamic response than passive pickups.
• Performance EQ Switch: Lets players select preset voicings for slap, pick, flat, finger or solo and saves time dialing tones mid-set.
• Perfectly Balanced Design: The ultra-comfortable body shape and weight distribution reduce fatigue when playing standing for long sets.
