Then I could only play it for a few minutes, not to piss the neighbors off. It does have that classic Plexi sound though! I love it! It sounds and reacts as close to my original as I have ever heard! It's great! I can crank this thing up without pissing anyone off! I used to have to wheel my original Plexi into the garage while I stood in the basement to get it up to the level where it needed to be.
You can barely hear it outside my house, it's so muffled. When I bump it up to 20 watts it's just noticeable louder, but that's it.
It does fill the room up with sound but is not too loud. On 5 watts I have the thing cranked full blast (everything on 10) through a 4x12 Marshall cab in the basement.
It's about as loud as a trumpet on the low setting. I'm not sure why people think this amp is loud or would even need to use a attenuator with it.
