I was familiair with the small Phil Jones Double Four BG75 combo, but I didn't know they also made this tiny Nanobass X4. I was looking for a good quality small practice combo with decent sound quality and bluetooth, so I just had to try one. These tiny combos aren't cheap, but they don't sound or feel cheap either.

The Nanobass looks gorgeous, especially in red or white Tolex. Build quality is excellent. Like the Double Four, this Nanobass unit feels solid, sturdy and well made. It has a nice weight to it. The speaker and radiator are covered, so you can't accidentally damage them. The power cord has an angled connector, which helps keep the power cord out of the way. I read some negative comments about the placement of the power connector, but I feel this is the best possible location for it. I'm glad they used a good quality standard connector type.

Turning the X4 on is completely silent. There's no hum, crackle or pop. When I put my ear tot the speaker, there's only a very soft hiss. Might be from my bass. I shouldn't put my ear that close a speaker, it's stupid. The Nanobass remembers the last setting. Bluetooth switches on, if that's what I last used and it connects to my phone quickly and reliably. No need for an extra cable connection between my phone or laptop and the combo anymore. Ready to go in just seconds, exactly what I had hoped for. I think the Double Four and maybe some other units could also really benefit from this bluetooth option. I like the combined volume/push AUX/BT button. Really smart, but I do find myself accidentally pushing it sometimes when I want to adjust the volume. It's quite sensitive. The little clipping led is very handy setting the correct input volume for your instrument.

Music via bluetooth and the auxiliary inputs sounds fine. You can really hear that the Nanobass has a full range speaker. There's bass and higher frequenties don't sound muffled. You can actually use it as a bluetooth speaker and I imagine the Nanobass sounds fine for other instruments too. I place it on a table or desk to get the speaker closer to ear height. Experimenting with the placement of the unit in the room will probably help you to get the best listening experience.

Remember it's only 35 Watts into a 4" speaker. The Nanobass is not going to make your pants legs flutter or lift any skirts. It just isn't very powerful and certainly not something you'd want to bring to a band rehearsal. However, it can fill a small room with the sound of your music and bass quite nicely. It's perfect as a super portable practice/travel combo and it might be just enough for a small acoustic session.

A bass guitar sounds good through the Nanobass, but you can hear some of the digital sound processing and compression that's going on. It's not a bad thing though. It makes the Nanobass sound very smooth and controlled. All in all I think this is a well executed idea to create a bass combo that not only sounds good and looks gorgeous, but fits in your backpack too. I found a battery powered USB-C version online (Japan I think), the X4C, that probably interests a lot of people, but for me the standard version is perfect.

It's so much fun to use this tiny combo!

At my old job, I didn't want to leave anything too expensive around my office (though nothing disappeared). At my new job, my brother gave me an office with a lock on the door. After much pondering, I decided the NanoX4 is what I need, so the order went in today (red). Bluetooth from the laptop (mostly streaming KSHE95) and plug in a Bass/Guitar/Harp if I want to. I'll also leave my 3-string CBG in a corner.

It will get used every day I'm in the office!...

I use my guitar into my D4. Works great. Just needs a little OD to tame it. Is the X4 like that?

How has this bluetooth receiver work out for you?
Easy-peasy set up w/ASUS Laptop my brother set me up with, works fantastic!

I think that anything that you plug into it will sound like the instrument - it doesn't seem to color the sound, BUT I have not cranked the gain to see if it ODs, but I doubt it?... (Edited to add) I haven't "played" through it, yet, or even "cranked it" to see how loud it gets ;) , so can't really be of help with the OD part.

It's tucked into a desk "corner" to my left when facing the laptop, so ~3' away (good volume where I sit, but you can't hear it in the hall with the door open). First thing I do when I get in is fire up the laptop, go to KSHE95 and click the "listen now" button, then the "play" button on that page. My laptop defaults to 100% volme, so I don't even get to 9:00 on the Nano volume. I noticed today how I could really hear the detail in everything from the kick to the cymbals - it certainly brings the whole package!

Absolutely no complaints/regrets! :D

I doubt it breaks up. The Double 4 gets screaming loud with guitar and doesn’t break up at all. I think it’s a little shrill. I just toss on a low gain drive pedal just to make it sound more electric guitar ish. I love it. Seriously considering the X4.

Exactly. Now I (think I) understand how OD could "tame" that. Thanks!

how do you think it would with an IPone vs laptop!

thanks

Intrigued. How deep would you say the “depth” of tone is on this little combo? I have a Blackstar Core ID Beam that I’m looking to replace as it can sound quite boxy yet boomy at the same time, especially in comparison to my larger, albeit not huge Headrush frfr-108.

I think the Blackstar (and my inexpensive old Edirol nearfield monitors) suffer from the fake bass 120hz boost to make up for the lack of real low end.

It's not going to get loud enough shake the pictures off of the wall, but sounds good to me. Probably does sacrifice some of the double-digit freqs for low mids, to some extent? Don't have experience with that other gear...

I just got the X4 and really like it. Sounds great on my desktop. For its size and weight it has very good lowend and overall sound fidelity. I had a Shuttle 3.0/10 under my desk for this purpose for years and this easily replaces it. It will also work for my couch rehearsals with the band. The bluetooth to run tunes in through the phone is pretty cool too. I got a "used" unit from Pitbull at a discount and I could not tell it was an open box.

Hi,
first post here, recently I got a Harley Benton jazz bass and I have started practicing with it

I am not a musician nor I intend to become one, I am just playing for the fun of it (and a bit of guitar/piano)

Currently I am listening directly through my audio interface (Motu M4) from monitor speakers (Yamaha HS5) or headphones (Sennheiser 58x) or using the VOX Amplug bass (sound-wise I prefer the first option with speakers or headphones, I don't really like the sound out of VOX Amplug)

So am thinking of getting a small bass amp only for practice and specifically in low volumes (appartment).

First option I have is Rumble 40 which is the cheapest option and can be found easily used even cheaper (but is not small enough ...)

Then I am considering Phil Jones: Nanobass X4 or Double Four because of the small factor: I like to be able to move it around the house easily, I don't care about getting loud, I will only use it in my appartment, so I can pay more for this but only if it meets the following criteria:

- I 'd like it to sound like a bass - not something that resembles a bass
- have a good headphone out
- be able to record about of it. X4 has no dedicated line out - only headphone out - has anybody tried to record with it?
- I like the bluetooth option of X4 but if Double Foure is much better in terms of sound (in low-appartment volumes) I can live without it.

In EU there is no DC option for Double Four so both are the same in terms of powering options.

So, the only differences (apart from size/2x4'' speakers vs one 4'') is the bluetooth option that X4 has, and the dedicated line out that Double Four has.

I like the size factor of X4 (and of course Double Four is not big at all).

I am between these two and also cosidering the Rumble 40 option (for the sound and the price- however I don't like the size of it)
