[Universal] I thought I'd use this for both practicing my bass, and listening to tunes. I found that the unit dosn't get loud enough for listening to music through the speakers. I returned the Bass Pack, which includes the extension speaker and power supply, and ordered the single FLY3Bass, which I love. I practice my bass with mp3 files of my band minus bass. Especially good when using headphones.

[20.32 lb] works great, using foam under battery cover as other reviewers said it can vibrate without batteries in place.


do notice a hum when volume is cranked up, both on A/C and battery, but not detrimental reminds me of the amps of old with a ground toggle switch

[Empty] I live in NYC and have larger cabs and heads. I got this little amp for being able to get on the subway without breaking my back. For the size, weight, and money this is a great little amp.for practice and low volume rehearsals.

[Empty] Nylon canvas over thick sturdy foam. Very protective. U-Bass fits perfectly.

[20.32 lb] Excellent price on an excellent product. The second mini cabinet takes it out from the standard plastic portable amp category into an easy to carry practice amp with some presence. Good range of sounds for an amp of this size. This one is a different breed from the clock radio sound many other practice amps suffer from. This is now my official vacationing practice bass amp of choice.

[Black] Have you ever become frustrated when folks power up an amp rack while a source is delivering a full-scale signal to it? The large LEDs in this unit are eye-catching enough to act as a console output pilot light which might catch enough attention to avoid the situation. There are even more useful applications for the unit... so don't write it off as a toy before trying it.

In our application, a 52kW amp rack is controlled by an innocent-looking key switch. Imagine that someone turns off the keyswitch and then uses the mains level controls as a handy headphone volume knob while the amps are off. Without the eye-catching LEDs displaying mains level, its easy for the next person to activate the keyswitch, deafening those in the path of the 52kW amplifier output.

[Universal] We installed this near the sound desk as a big visible vu meter of the output of audio going to our livestream. It works quite well and doesn't seem to add any noise to the system (or if it does, its negligible enough to not matter once the audio is compressed to the livestream). Plus, its 5x cheaper than anything else like it!

[Black] This case is exactly what I wanted to make sure my bass will never suffer from outside influences when on the move. Sturdy is an understatement. Cradled in the lap of luxury surrounded by the best materials available. Latches that don't quit and it's TSA approved for travel on airlines. Who could ask for more!

[Empty] This type of case offers the best of both a hard case and a soft bag. It conforms snuggly to the shape of a Kala Baritone Uke or a U--Bass. It provides almost all of the protection of a hard case, but weighs very little more than a bag. It also has a rear-mounted strap for carrying it over your shoulder. There is a small, covered, internal accessory box under the instruments neck location, and a generous zippered accessory pouch on the front of the case. This case will provide excellent protection for an instrument as long as isn't crushed by a considerable weight. Scrapes, scratches, hard bumps, and even drops from shoulder height will do no damage to the instrument inside, and no functional damage to the case itself. Have no doubts, this is real protection for you Kala Baritone or U--Bass.

[Black] I know it seems kind of expensive, but if you want to clip the Go blu to your clothes you kind of need it. That being said, it is really nice quality. It's two-tone stitched genuine leather. It looks hand made. The only quibble I'd have is you can't push the Go blu too far down in the case or the volume knob will rub. Also, you pretty much have to turn the knob from the top because it doesn't stick out far enough from the case. The button in the knob is full accessible. And the other buttons can be pressed through the leather and the case has little markings where they are.
