Phil Jones Bass X4C Nanobass 1x4 35W Bass Combo Amp Black
Impossibly compact 35-watt bass combo with four-inch speaker that defies physics and expectations. Phil Jones Bass's Nanobass delivers legitimate bass tone and volume from a lunchbox-sized package—perfect for practice, fly gigs, and acoustic sessions where portability trumps stage volume.
Pros & Cons
Pros
- +Four-inch speaker punches well above its size class thanks to tight enclosure design and Phil Jones' proprietary driver technology
- +35 watts of digital power provides surprising headroom for practice, coffee shop gigs, and acoustic jam sessions
- +Physically the smallest legitimate bass amp on the market—fits in a backpack and weighs less than your pedalboard
- +Clean, accurate tone reproduction makes it viable for double bass, fretless, and acoustic bass amplification
- +At $420, it's unique in its category—no direct competition for ultra-portable bass amplification
Cons
- −Not intended as your only amp—won't compete with drummers or hang on rock stages without PA support
- −Four-inch speaker can't reproduce deep low-end extension; expect rolled-off sub-bass response below 60Hz
- −Digital power amp may sound sterile to players preferring tube warmth and compression
- −Limited EQ and features versus traditional practice amps—basic controls prioritize portability over flexibility
The Verdict
The Phil Jones Nanobass is proof that bass amps don’t need to break your back to be useful. That four-inch speaker has no business sounding this good—it’s a triumph of enclosure engineering that delivers clean, defined bass tone from a package smaller than most lunchboxes. But let’s be clear: this isn’t replacing your Ampeg SVT rig. It’s a specialty tool for specific scenarios—practice at home without disturbing neighbors, fly gigs where you can’t check luggage, acoustic sessions where a full combo is overkill, or double bass amplification where accuracy matters more than volume. At $420, it fills a niche no other manufacturer addresses seriously. The Legendary score (90) reflects its excellence within its intended use case, not as a do-everything amp. If you travel frequently, play acoustic gigs, or live in an apartment where volume is measured by complaints-per-hour, the Nanobass is essential. For everyone else, it’s a curious novelty that’ll gather dust after the initial “wow, this is tiny” moment wears off.
