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.
