Independent shopping perspective
The Korena take
Finished in Transparent White, the TRBX504 is a four-string bass built with a solid-mahogany body and a five-piece maple/mahogany bolt-on neck. Its YGD H5 Alnico pickups and active/passive circuit provide two operating modes with matched output. The onboard layout includes volume, pickup balance, bass, middle, and treble controls; switching to passive mode repurposes the treble control as master tone. A battery-alert LED sits on the back panel. The 19 mm bridge spacing, 38 mm nut width, and 34-inch scale are specified for this model.
Strong match
Who this is for

- Players who want pickup balancing and three-band bass, middle, and treble adjustments onboard.
Consider the trade-offs
When to look elsewhere
