Independent shopping perspective
The Korena take
Built around a passive Monstertone-J pickup set, this J-4 gives players two volume controls and a master tone with a push-pull setting for a vintage-leaning option. Its alder body pairs with a 34-inch maple Thin C neck, while dual carbon-fiber reinforcement and an accessible truss rod support neck adjustment. The fixed custom bridge accepts either string-through-body or top-loaded strings, letting you choose between the two listed stringing paths.
Strong match
Who this is for
- Players who want a passive four-string bass with separate pickup volumes and a push-pull tone control.
- Stage or rehearsal setups where either string-through-body or top-loaded strings suit the chosen setup.
Consider the trade-offs
When to look elsewhere
- Players who need an included case or gig bag.
