OK folks. I don't get it. On paper the Amplifi 150 has all the goods to sound well, good. But, I've got an open back Spider Jam that in my opinion mops the floor with it. No matter what dirt I add it just seems flat. I've got a Roland Cube that also trounces the Amplifi. I suppose the bluetooth playback with full range drivers is a bonus but guess what? The bluetooth range is awful. A good practice amp for a newbie but that's all I see at this point. If you've got settings that let this thing breath let me know but I've tried all the high gain models and boosts. Tempting to crack it open and slap in an Eminence Governor .
