Small good sounding battery amp?

[rpjazzguitar]

The LJ needs 80W for full power, I expect, but Class D amps draw very little current while idling. I would think the 80W is the maximum it would ever draw, and usually far less. If the volume is only turned up halfway, it should never approach that. A tube amp, OTOH, draws a lot of power even with nothing plugged into it, and even with the standby switch off. All that does is cut power to the output transformer, everything else is powered normally. I think Class D is the way of the future, for many reasons.

Is the LJ a Class D amp? I couldn't find a definitive answer on that.

It is.

So, just in case it's of interest to anyone else, after some hours playing with the Nux Mighty Lite, I dialed in a lovely clean warm sound quite easily. The only effect I added was a little reverb. It has a phone app that controls it via Bluetooth Midi, and also comes with some sample backing tracks that play via Bluetooth audio through it. I was soon jamming along nicely. It's only 3 watts, and that translates to about 2 to 3 times louder (my guess) than the guitar played acoustically, a little less if you keep it real clean. More than enough for practice and general home use.

The extra features, like the tremolo, phasor, chorus, vibrato all work well, and it has four delays and four reverb types, plus a noise gate. The amp itself has a crunch mode, and a metal distortion mode which I will never use. It has a drum machine inbuilt that I will probably never use.


Interesting, like I saw mentioned in a youtube video, because it is a modeling amp, it does emulate things like a little bit of crunch on the top when you drive it hard in clean mode, just like any small combo amp does. It allows a nice variation in sounds controlled by touch as you play the guitar.

So, a battery modelling amp that comes with an AC adapter, plus it can be powered from the USB connector that also allows firmware updates. When powered from USB it has less volume though.

I tried a lithium-ion power station, horrible hum even with humbuckers. Both inside and outside, I was using a Quilter micropro. I really wanted it to work but it didn't.

Was your power station spec’ed as having a pure sine wave?

I’ve been using this one (Roland Mobile Cube). Nice clean sound, great battery life too. Works great with guitar, acoustic, and steel guitar (even sounds good with pedal steel). Came to my attention because several Hawaiian steel players use this for small combo work.

thats the one I use. Surprisingly good and hilariously small

It may also be worth checking out guitar sound systems

they have little amps that run off a lithium ion pack.

Roland’s Street Cube- or is it Cube Street - is powerful and goes long. If you use a class D you can buy the Makita 18W connector for its batteries on AliExpress, add a pure sine 100W (150 peak) with low no-load draw and 90% or more efficiency. Friend of mine makes these for professional street performers. (He also does outdoor rave parties on solar, very very loud for a crowd of 300 outdoors. )

My wife uses a Bose S1 Pro for her vocals when we rehearse in house. I have plugged in a few guitars and it sounds pretty nice. For a busking duo this would absolutely work fine. And you can still hook up an Iridium if you want more amp-like sounds.
