    5892429F-63ED-4D65-B607-589D7B3EE7BF.jpeg Anyone using the JHS Little Black Amp box? It works as directed. It’s plugged into my HRD. I’m running my volume on 4 from practice the other day. Normally, I’d be under 2 - The HRD usually has two settings, Loud AF or off. I am getting great tone at a good level, very adjustable. Con so far is a really loud hum. You don’t hear it playing, but in between songs, it’s a bit obnoxious. I’m gonna have to think about this.

    It's a volume control that plugs into the effects loop to tame a LAF amp. It pretty much does the same thing as the volume knob that is built into the amp.

    ...so it's basically like using a volume pedal in the loop. Nifty.

    That's the same issue I have with my Classic 30 in my small practice room.

    Is it possible you have a defective unit that causes it to hum? Maybe you should email the manufacturer about that.

    How does that work?
    Does it lead some of the signal to ground?

    I imagine it works like a volume pedal, but with a knob instead of a rocker for your foot. If you have a volume pedal you can run it through your effects loop, crank your amp to get the tubes cooking (if you have them), and use the volume pedal to bring the amp down to a decent room level for practice.

    Correct. You can run the preamp hot and still have volume control. A volume pedal could go in. The effect loop and do the same thing. If it’s in your pedal chain, then it’s decreasing the signal before it even goes to the preamp. That’s different and the same as just not having anything in that chain turned up.

    Update. I bought a cheap power conditioner and have chased most of the noise away. The little box is pretty cool. Very gritty distortion pedals, the real sweet tone is just DynaComp+TubeScreamer clean. I get a clean but creamy tone running the useless channel volume on 4 and the black box tweaked to tolerable. It might be worth a try for someone else too.
