Our take on the Yamaha TRBX304 4 String Electric Bass

The TRBX304 is Yamaha's mid-range 4-string active bass, built around a solid mahogany body, a 5-piece maple/mahogany neck and two YGD M3 ceramic humbuckers. Its signature feature is the 5-way Performance EQ switch, which swaps in preset tone curves so you can move from fingerstyle to slap without heavy knob work. It suits players who want one bass that covers rock, funk and pop gigs, and it competes with active basses like the Ibanez SR300E and Squier Contemporary Active Jazz Bass on switching flexibility rather than premium hardware. Owners tend to praise the neck, balance and value; the preamp and stock strings draw the most criticism.

Questions and answers

Is the TRBX304 active or passive?
It is active, with a 9-volt preamp and the 5-way Performance EQ. A switch lets you run it passive if the battery dies.
How does it compare with the TRBX305?
The 305 is the 5-string version with the same body, neck construction and electronics. Choose the 304 if you only play 4-string.
Is it good for beginners?
Yes, if you want an active bass from the start. The neck is comfortable and the presets make it easy to find a usable tone.
What is the Performance EQ switch?
A 5-position selector that applies preset EQ curves for styles like slap, fingerstyle and pick. It works alongside the normal bass, mid and treble controls.
Does it need a battery to make sound?
No. With the active/passive switch set to passive, the pickups still work without a battery.
What comes in the box?
The bass, a truss rod tool and basic documentation. A gig bag, cable and strap are usually not included.
Where is the Yamaha TRBX304 4 String Electric Bass cheapest?
At eBay, for $349.99, 22% under what the other stores charge, as of our latest check.
