Not much of a guitar player (I'm a drummer...), but I'll confess to being more than partial to a nice, vintage, Hiwatt amp. I had a Custom 50 for quite a while; it got left behind when I moved to France, mid '70s. Our min bass amp is a Hiwatt DR205, a 200w PA head, with KT88 valves. These were useful at one time for demolishing WWII bunkers along the Normandy coastline..!
Nowadays I get by with a Roland JC60, or directly into the PC through my pedalboard when I'm recording stuff. S'not often, these days, though.
I've a Bassman 50w, too, but it's been in retirement for some tie now. I must fetch it out again soon...
