This Harley Benton B-650FL is a seriously impressive fretless bass for the price. The active preamp gives you a surprising amount of tonal shaping, while the alder body delivers a solid, warm low-end. It's a fantastic option for players wanting to explore fretless without a huge investment, especially those into Jaco-inspired funk or smooth jazz.

Frequently Asked Questions

The black walnut fingerboard is slightly softer than rosewood, so it will have a unique 'give' – it’s quite responsive but might require some adjustment if you’re used to harder fingerboards.
The active mode significantly boosts the output and allows for more precise EQ shaping, but the passive mode still sounds very good with a more natural, vintage tone.
The included strings are decent for getting started, but upgrading to higher-quality strings will noticeably improve the fretless’s sustain and overall feel.
