Independent shopping perspective
The Korena take
Built around a five-string layout, the TRBX505 pairs a sculpted solid-mahogany body with a five-piece maple/mahogany neck. Its YGD H5 Alnico V pickups feed an active/passive preamp, so you can move between modes while retaining matched output. In active mode, the controls provide tone-shaping range; passive mode changes the treble control to a master tone. A low-battery indicator helps flag power before it becomes an interruption. The 18 mm string spacing, 43 mm nut, and 34-inch scale define its playing layout.
Strong match
Who this is for
- Players who want a five-string bass with selectable active and passive operation during a performance.
- Bassists shaping sounds from the preamp while retaining a passive-mode master tone control.
Consider the trade-offs
When to look elsewhere
- Players specifically looking for a four-string bass.
