Description

We were among the very first dealers to bring Phil Jones amps to the US market, and we've brought them back on board!

I'll be updating the specs on this amp with my personal descriptions very soon. In the meantime, here's the information as provided by PJB.

 

Lightest Portable Tone-To-Go, A Mini Marvel - and NEW Rechargeable Power Option!

Nanotechnology breaks the sound barrier with the X4 Nanobass Multi Instrument Combo Amplifier, which is the most compact and portable combo amplifier ever designed by Phil Jones Bass for desktop and practice applications. It is a highly efficient mini engineering marvel that redefines transportability and “Tone To Go”.  It is a 35 Watt amplifier with a 4” speaker and 3 Band EQ that not only rocks with bass; it will also provide dazzling tone for other instruments including guitar, ukulele, violin, and electronic drums.

The practical and versatile design includes an auxiliary input compatible with iPads, iPods and drum machines, and is Bluetooth equipped for music listening enjoyment and other applications.  PJB’s proprietary NeoPower 4-inch speaker delivers full frequency range that achieves ultimate tonal clarity and transparency for instruments as well as high-fidelity sound to any source fed into the auxiliary and Bluetooth inputs.

The X4 weighs just over 5 lbs and is small enough to fit in a backpack. It is available in Black, Red, and White colors. As with all products in the PJB family it is constructed from the highest quality materials and built to provide years of enjoyment and “Tone To Go” anywhere in the world with its built in worldwide AC voltage input.

AMPLIFIER FEATURES

  • PJB N52 Neo-Power 4 inch speaker driver
  • 35 watts Digital Amp with DSP-based active crossover and dynamic range control
  • PJB 3 Band EQ.
  • Stereo Aux input for Drum machine or iPod/Smart phone player.
  • Bluetooth5.0 (aptX HD)
  • Worldwide AC voltage Input. (100~240V)
  • NEW Rechargeable Power Option for use "off grid" - see below for specs/recommendations

About the USB Power Input on the NANOBASS X4C (for off-grid/power bank operation)

The USB C to Powerbank option on the X4C provides you with the freedom to play anywhere, making it a perfect choice for jamming or busking when AC isn’t available (power bank is not included and must comply with the specifications provided).

The USB Type-C port is for Power Delivery from a 20-Volt Laptop power bank. The higher the capacity in mAH, the longer the amplifier will be able to work. 20,000MAH will be a good start. We suggest a unit that has the capacity to supply at least 65 watts, (preferably 100 watts for best sound quality) Time duration of operation will depend on how loud the amplifier is playing.

Again - the POWER BANK IS NOT INCLUDED and must be PURCHASED SEPARATELY.

    Great for certain applications

    Posted by Jonathan Dreyer on Jun 19th 2024

    I bought this for two reasons: First, to use as a monitor because I can't usually hear the highs when standing in front of my cab, and second, as a practice amp with my EUB when traveling. It works very well for those situations. It might also work when you need just a little help in a very small venue with a small, quiet band, but I haven't tried that. The main issue of course is that it's completely missing most of the lowest octave of the bass, but for monitoring and practicing, those aren't big issues. It's also not very loud, even at its loudest. Why did I not get the even smaller PJB Ear Box instead? One reason is that it's just a speaker, not an amp, so it wouldn't work as a practice amp. The other is because the Ear Box is not really that portable because you seem to really need a mic stand for it. With the NanoBass, I have rigged up a little stand that angles it up at 45° that I just sit atop my amp+cab. Maybe that would work with an Ear Box but they say you have to get really close to it.
