Yeah it can be LOUD! LOL But I haven't gotten any complaints yet. In the evening, I switch it down to the 1/2 watt setting. And that's certainly not a whisper.
The "Tilt" knob is intriguing. I've never had, nor played a 4 input Plexi, so I can compare it to the actual feel of one. But this amp is supposed to sound like a jumpered Plexi by using the tilt knob. Interesting.
