"Compact, high-fidelity 70W bass combo that punches well above its size for practice and small-stage use."
I tested the Phil Jones BE-17 Bass Engine with the idea of finding a truly portable practice amp that still sounded like a bass amp - not a tiny PA speaker pretending to be one. In daily use I found a surprising amount of low-end presence for a 7-inch-woofer combo, hands-on tone controls that actually move the sound in meaningful ways, and a Bluetooth input that keeps rehearsal setup annoyances to a minimum. My use case was home practice, small rehearsals, and a couple of low-volume acoustic gigs where I needed something lightweight but clear and musical.
First Impressions
The BE-17 arrives as a compact, neat package - smaller than most fellow players expect when I tell them it's a 70-watt combo. Out of the box the cabinet feels solidly built, the curved steel grille gives confidence against accidental kicks, and the control layout is straightforward - input level, three-band EQ, master and dedicated line/AUX/Bluetooth controls. I weighed and carried it around rehearsal and it truly lives up to the light footprint Phil Jones advertises - it is noticeably easier to move than many 1x10 practice combos.
Build Quality & Design
I was pleasantly surprised by the BE-17's build relative to its price and weight - the curved steel grille and kick-proof cabinet give it a feel of durability I trusted on the floor. The finish on the red model I used resisted scuffs during transport and the control knobs have a reassuring click and travel; the three-way input switch (Mute / Active / Passive) is robust and useful when swapping basses with different output levels. Phil Jones also uses a proprietary 7-inch woofer coupled with a 3-inch high-frequency driver, which explains why the cabinet produces a wider frequency response than you'd expect from a speaker that size.
Features & Controls
The amp's control set is compact but thoughtful - input level, Bass/Mid/Treble with generous +/-15 dB ranges, and a master volume, plus separate level control for line-in/Bluetooth. Bluetooth 5.1 with aptX HD support made streaming backing tracks clean and nearly CD-like in quiet practice; the BE-17 also offers L+R line inputs for drum modules or stereo sources and a line-out for DI/recording. A headphone output allows private practice and the Line-Out is useful if you want to send a balanced-ish signal to a mixer or interface without fuss.
Playability & Usability
Playing through the BE-17 felt immediate - the input gain and three-way active/passive switch make it easy to match everything from a passive P-bass to an active modern instrument without hunting for gain. The mid control is the star for me - sweeping a little provides clarity for fingerstyle parts or thump for slap when needed, and the treble shelf adds articulation without sounding brittle. For bedroom to small-venue levels the amp stays clean up to a good headroom point, and when pushed the sound is musical rather than harsh.
Real-World Experience
I used the BE-17 across several contexts - home practice, a rehearsal with drums, and for front-of-house through a small PA at a coffeehouse gig. At home it handled low-volume practice with convincing lows and clear articulation; at rehearsal it cut through a stripped band surprisingly well when I emphasized mids and tweaked the master. For the coffeehouse gig I ran a DI from the amp's line-out to the FOH board and the engineer reported a usable signal that retained my tone, which made setup painless and removed the need to mic the tiny cabinet on stage.
The Trade-Offs
No amp is perfect and the BE-17 has natural limits - a 7-inch woofer will not replace a 12-inch cabinet for full-throttle stage volume or sub-bass extension. If you routinely need chest-rattling lows at medium-to-loud gigs you will bump into limits - the BE-17 sings in the 30Hz+ range but doesn't reproduce the extreme sub-bass of larger speakers. Also, while Bluetooth is excellent for backing tracks, relying on Bluetooth in a dense RF environment can introduce pairing flakiness that I occasionally encountered in a crowded cafe with many devices.
Final Verdict
Overall the BE-17 is one of the most convincing compact bass combos I've used - it balances portability, fidelity, and features in a way that makes it a great daily driver for practice and small gigs. I recommend it to players who need a reliable, lightweight amp that still sounds like a bass amp and who value clear, responsive tone over brute force SPL - it is ideal for home players, gigging singer-songwriters, and as a tonal reference on small stages. If you need massive stage volume or deep sub-bass at medium-to-high loudness, pair it with a dedicated sub or larger cabinet; otherwise I found it to be a superb little workhorse.
Helpful Tips & Answers
- Will this amp handle an active bass without distorting?
- Yes - I switched between passive and active basses using the mute/active/passive switch and could dial the input so it stayed clean; the switch is handy for taming hot pickups quickly.
- Is the Bluetooth good enough for jamming along with tracks?
- In quiet environments the Bluetooth (aptX HD) is excellent for practice tracks and sounds near-CD quality; in RF-heavy venues I still prefer a wired line-in for reliability.
- Can it be used as a DI to front-of-house?
- Yes - I used the line-out to feed FOH and it delivered a clean, usable signal that preserved my EQ choices, which made live setup straightforward.
- How loud is 70 watts in a small club setting?
- For small clubs and coffeehouses it's perfectly adequate when pushed; for mid-size rooms you'll want an extra cab or DI to FOH for more authority and low-end weight.
- Is the cabinet durable enough for gigging?
- The steel grille and solid construction held up fine during repeated transport and light stage use, though I still recommend a cover for long tours or rough handling.
- Does it come with a cover or accessories?
- My unit came with a simple slip cover included in the package I received, which is handy for short trips and shelf storage.
- How portable is it really?
- At roughly 15 pounds and compact dimensions I carried it easily between jobs and it fits on most chairs and small amp stands without fuss.

Review of Phil Jones X4 Nanobass WH
I spend a lot of time chasing compact practice rigs that do not compromise on clarity, and the X4 Nanobass sits squarely in that pursuit - a 35 watt, 4 inch mini combo that promises serious tone in a backpack-ready package. My use case was desktop practice, quick apartment rehearsals, and plugging in a secondary instrument, so I treated it as a portable tone tool and evaluated how well it balanced size, feature set, and sound quality.
First Impressions
The first time I set eyes on the X4 I was struck by how small and solid it felt - it is genuinely pocketable for an amp, and the white finish I used looks clean without being precious. Powering it up revealed a surprisingly open voice for a single 4 inch driver and the controls are straightforward - input, aux/bluetooth level, bass, mid, treble and master - which made dialling in a useful sound very quick. That immediate compactness paired with clear, articulate output set the tone for all of my subsequent testing.
Design & Features
The X4 is built around a PJB N52 Neo-Power 4 inch driver and a 35 watt digital amp with onboard DSP-based active crossover and dynamic range control - those are the core design choices that explain why it sounds full despite its footprint. It offers a 3-band EQ with very generous +/-15 dB ranges, an aux input plus Bluetooth 5.0 with aptX support for streaming practice tracks, and a headphone output for silent practice. The unit is mains-powered with worldwide 100-240V support and measures roughly 160 x 200 x 198 mm while weighing just over 2.4 kg, so the construction feels dense but not heavy.
Build Quality & Protection
Physically the cabinet feels well put together - the tolex, corners and grille are fitted tightly and there is little flex when I press on the enclosure. The controls have a reassuring resistance to them that avoids feeling toy-like, and despite its small size the amp has enough mass that it does not vibrate around when pushed. I would not call it rugged road-case level, but for regular home use and transport in a backpack it inspires confidence.
Comfort & Portability
Carrying the X4 is barely an inconvenience - it fits under my arm and slides into a larger backpack with room to spare for cables and a tuner. Because it is compact and light I found myself grabbing it much more often than a heavier practice rig, which made practicing more frequent and less of a production. The lack of a heavy handle and the small footprint are deliberate trade-offs and they pay off if mobility is your priority.
Sound & Tone
Sound is where the X4 pleasantly surprised me - for a single 4 inch driver the speaker and DSP design produce a transparent midrange and a focused low end that reads my bass lines clearly. The bass shelf is tuned around 100 Hz and while you will not get subwoofer weight here, the amp gives realistic string definition and attack so slaps, fingerstyle and pick work well in a practice setting. The 3-band EQ is potent - +/-15 dB is a lot - and I used modest boosts rather than extreme settings to keep the amp sounding natural; pushed hard the DSP and dynamic control keep things from flubbing out, which is impressive engineering for a box this size.
Real-World Experience
I used the X4 at my desk with a passive precision-style bass, in a small rehearsal room with an acoustic guitar, and in an apartment where headphone practice was essential - it performed well across all of these scenarios. On low-volume apartment practice the tonal clarity and responsive EQ made it feel like a much larger amp, and the headphone output is handy for late-night sessions. In a small room with a drummer it lacked the physical bottom-end to replace a full PA or stage cab, but it still provided clear monitor-level sound for tone checking and compact stage setups.
The Trade-Offs
You will not get sub-bass authority or huge headroom - this is a 35 watt amp with a 4 inch driver, and that reality matters if you play low tunings or need stage-level volume. Bluetooth streaming is convenient but I noticed occasional small latency when using it for monitoring, so I kept it primarily for playback rather than direct monitoring during recording. Finally, while the EQ is powerful, extreme boosts can expose the speaker limits, so sensible hands-on EQing gives the best results.
Final Verdict
The X4 Nanobass is a focused product that does exactly what it sets out to do - deliver transparent, portable practice tone with useful features in a tiny package. I recommend it to bassists and multi-instrument players who need an honest-sounding, ultra-portable practice amp, or as a secondary amp for tone-checking and small-room gigging; it is not a replacement for a full-sized stage rig but it is a brilliant companion for everyday use. If portability and clarity are your primary concerns, I found the X4 hard to beat for its size and feature set.
by Musicngear Verified Community ReviewsHelpful Tips & Answers
- Is the X4 loud enough for small rehearsals?
- For small rehearsals it provides clear monitor-level sound, but it will not match the low-frequency energy or SPL of a full cabinet if you need stage volume.
- Can I use it as a headphone practice amp?
- Yes - the headphone output works very well for late-night practice and maintains the amp's natural voicing when listening silently.
- Does Bluetooth affect sound quality?
- I used Bluetooth for backing tracks and found it convenient; audio quality is good, but I noticed slight latency so I avoid it for critical live monitoring.
- How flexible is the EQ for different instruments?
- The 3-band EQ with wide +/-15 dB range lets me shape bass, guitar, or ukulele tones effectively, though I prefer modest adjustments to keep the speaker sounding natural.
- Is the amp durable enough to travel with?
- It feels solid for frequent transport in a bag, but I would not treat it as luggage-level rugged without extra protection.

Review of Phil Jones Bass Combo S-77
I’ve been using the Phil Jones Session 77 (S-77) as my go-to small combo for practice, bedroom recording, and the occasional coffee-shop gig, and what struck me first was how much useful bass information this little 100-watt amp can deliver without fuss. It’s a single-channel, 3-band EQ design built around two small PJB woofers and a tweeter that aims to reproduce the full range of the instrument with clarity rather than colored grit - ideal for players who want a faithful, transportable monitor that still has enough low-end presence to sit in a mix.
First Impressions
The first time I set the S-77 up I expected thinness because of the small 7-inch drivers, but the cabinet and the PJB-designed woofers give a surprisingly solid low-mid weight - not a subwoofer chest-thump, but a focused, articulate low end that reads well in a room or into a DI. The unit is compact and solid-feeling; at roughly 17 x 11 x 12.5 inches and about 28 pounds it’s light enough to lift in one hand yet robust enough to feel like a proper piece of kit for rehearsals and small gigs. The universal AC capability (100-260V) and the simple control layout signaled to me that this was built for straightforward, global use.
Design & Features
Phil Jones kept the control set intentionally minimal - input, an Input Level with a Mute/Passive/Active switch, a 3-band EQ (bass/mid/treble), master, and a dedicated AUX level for backing tracks. There’s also a line-out and a headphone output, which I found handy for silent practice and direct recording. The front has PJB’s perforated steel grille and a slightly angled baffle that makes onstage monitoring more useful than a flat box. I appreciated the thoughtful touches like the mute function and the clip indicator - small items that make the amp feel professional in daily use.
Playability & Usability
Using the S-77 is refreshingly quick - I could switch between my passive and active basses with the sensitivity switch and the amp tracked dynamics well, responding to my attack and fingers without sounding compressed unless I pushed the master very hard. The EQ is broad and musical - bass adds weight without getting muddy, the mids give the instrument its voice, and the treble adds clarity for slap and pluck articulation. For pedalists, it behaved predictably; overdrive or envelope-type effects need to be tamed in front of the amp to avoid too much top-end hash, but that’s true of most compact combos.
Real-World Experience
I used the S-77 for a few weeknight rehearsals, some direct-to-interface recording and at-home practice sessions. In small rooms and coffee-shop-style shows it sat nicely in the mix - the mid-forward character ensured my lines cut through without having to crank the master. Through headphones and DI I found the amp’s tonal signature to be quite transparent, which made it easy to match recorded tones to what I heard live. The AUX input is a simple but effective feature for playing to tracks; the separate AUX level control kept the balance predictable when I needed click or backing track playback.
The Trade-Offs
There are honest compromises - the S-77 won’t replace a high-power 12- or 15-inch cabinet for large venues or players who depend on extreme low-frequency energy. Its small woofers are designed for clarity and definition rather than subsonic extension, so if your music depends on huge, room-shaking lows you’ll want a larger cab or PA support. Also, the single-channel straight-ahead design limits onboard sculpting compared with more feature-heavy combos, so players who want built-in compression, shape filters or multiple voicings may find it too basic.
Final Verdict
The Session 77 is one of those rare little combos that does exactly what it sets out to do - offer a faithful, compact, and portable bass solution for practice, small gigs, and direct recording. I’d recommend it to gigging players who need a reliable monitor that won’t dominate a car trunk, to educators and home players who want clarity and a small footprint, or to anyone looking for a high-quality travel/practice amp that still sounds credible onstage. If you require seismic low-end or advanced onboard processing you should look higher up the product ladder, but for honesty of tone and everyday practicality the S-77 impressed me.
by Musicngear Verified Community ReviewsHelpful Tips & Answers
- Is the S-77 loud enough for rehearsal with a full band?
- For typical small-room rehearsals it’s adequate - I could be heard through drums and rhythm guitars, but for loud bands or larger rooms I used a DI/PA or a larger cabinet to provide far more SPL.
- Will it handle active and passive basses?
- Yes - the Mute/Passive/Active switch makes swapping between active and passive instruments seamless and keeps the input stage behaving correctly for both types.
- Can I use it for direct recording?
- I recorded DI tracks using the line-out and the amp tracked very closely to what I heard in the room, which made matching recorded and live tones straightforward.
- How portable is it for frequent gigging?
- At about 28 pounds and compact dimensions it’s very portable - easy to lift in and out of a car and manageable on stage without help.
- Does it have any protective features for the drivers?
- The amp uses a perforated steel grille and a robust cabinet; I felt comfortable using it as a stage monitor without worrying about the speakers getting knocked.
- Is the AUX input usable for backing tracks?
- Yes - the separate AUX level control makes balancing tracks easy and I used it often for practice and backing-track gigs.
- What kind of warranty or support does it come with?
- From my experience and the documentation it carries a manufacturer warranty and clear support contact information for service questions.
