How things change.
Below is a photo of my bass amps:
The one behind is my old one. It is from the late '70s/early 80s, and puts out upto 65 watts when really cranked up. Both parts weigh an absolute ton.
In front is the new one. This one does 400 watts and also has loads of built in clever stuff. It also weighs less that each part of the old amp. And it is loud - even turned down low I could feel the floor vibrating - and our floor is made of concrete!
I will try to post a video to show off how wonderful it is very soon.
